This file version: $Id: CHANGELOG,v 1.1.1.1 2007-02-05 13:34:43 inonit%inonit.com Exp $
Changes since Rhino 1.6R5
=========================
- Added org.mozilla.javascript.PolicySecurityController as a concrete
implementation of an org.mozilla.javascript.SecurityController and the
preferred way of integrating with Java security architecture.
- When no security controller is in use, generated classes and scripts run in
the ProtectionDomain of Rhino classes.
- Wrapped access to system properties and creation of class loaders into
AccessController.doPrivileged() to nicely play in secured environments.
- Added implementation of __defineGetter__ and __defineSetter__ to match
SpiderMonkey. __lookupGetter__ and __lookupSetter__ are not
implemented, nor are the JS get and set keywords. Also see #224334.
- Fixed #318305: ScriptOrFnNode class reports bad end line number
- Fixed #352319: Rhino threw a ClassCastException when a continuation captured
from a catch() block was restarted.
- Fixed #340561: <Function>.prototype should not be DontEnum
- Fixed #342807: Could set line number/source file in thrown JavaScript Error
- Fixed #350580: importPackage Ambiguous import error fix
- Fixed #351664: Rethrown JavaScriptException's toString() returns
"[object Error]"
- Fixed #353300: Rhino now implements the ECMA-262 mandatory
String.localeCompare
- Fixed #353002: Outdated Information on BSF, Update Requested, Text Suggestion
Enclosed
- Fixed #358058: JavaScript debugger's text source editor allows tab key
presses
- Fixed #359411: LazilyLoadedCtor is not serializable
- Fixed #360568: Make swing debugger easier to subclass and extend
- Fixed #361574: Typo in Parser.java
- Fixed #361616: toLocaleUpperCase/toLocaleLowerCase is not supported

# Makefile for javascript in java.

# intended to be called by this makefile with the proper CLASSDIR,
# PATH_PREFIX etc. variables. Makefiles in subdirectories are

# variable set to the subdirectory where the makefile is located.

<title>Scripting Java</title>
</head>
<body>
<h1>Scripting Java</h1>
<p>This paper shows how to use Rhino to reach beyond JavaScript into
Java <a href="#ref1">[1]</a>. Scripting Java has many uses. It allows
us to write powerful scripts quickly by making use of the many Java
libraries available. We can test Java classes by writing scripts. We
can also aid our Java development by using scripting for <em>exploratory
programming</em>. Exploratory programming is the process of
learning about what a library or API can do by writing quick programs
that use it. As we will see, scripting makes this process easier.</p>
<p>Note that the ECMA standard doesn't cover communication with
Java (or with any external object system for that matter). All the
functionality covered in this chapter should thus be considered an
extension.</p>
<h2>Accessing Java packages and classes</h2>
<p>Every piece of Java code is part of a class. Every Java
class is part of a package. In JavaScript, however, scripts exist outside of
any package hierarchy. How then, do we access classes in Java packages?</p>
<p>Rhino defines a top-level variable named <code>Packages</code>. The
properties of the <code>Packages</code>
variable are all the top-level Java packages, such as <code>java</code> and
<code>com</code>. For example,
we can access the value of the <code>java</code>package:</p>
<pre>
js&gt; Packages.java
[JavaPackage java]
</pre>
<p>As a handy shortcut, Rhino defines a top-level variable <code>java</code>
that is equivalent to <code>Packages.java</code>.
So the previous example could be even shorter:</p>
<pre>
js&gt; java
[JavaPackage java]
</pre>
<p>We can access Java classes simply by stepping down the
package hierarchy:</p>
<pre>
js&gt; java.io.File
[JavaClass java.io.File]
</pre>
<p>If your scripts access a lot of different Java classes it
can get awkward to use the full package name of the class every time. Rhino
provides a top-level function <code>importPackage</code> that serves the same
purpose as Java's <code>import</code> declaration. For example, we could
import all of the classes in the <code>java.io</code>package and
access class <code>java.io.File</code>
using just the name <code>File</code>:</p>
<pre>
js&gt; importPackage(java.io)
js&gt; File
[JavaClass java.io.File]
</pre>
<p>Here <code>importPackage(java.io)</code> makes all the classes in
the <code>java.io</code> package (such as <code>File</code>)
available at the top level. It's equivalent in effect to the Java
declaration <code>import java.io.*;</code>.</p>
<p>It's important to note that Java imports <code>java.lang.*</code>
implicitly, while Rhino does not. The reason is that JavaScript has
its own top-level objects <code>Boolean</code>, <code>Math</code>,
<code>Number</code>, <code>Object</code>, and <code>String</code> that
are different from the classes by those names defined in the
<code>java.lang</code> package. Because of this conflict, it's a good
idea not to use <code>importPackage</code> on the
<code>java.lang</code> package.</p>
<p>One thing to be careful of is Rhino's handling of errors in
specifying Java package or class names. If <code>java.MyClass</code>
is accessed, Rhino attempts to load a class named
<code>java.MyClass</code>. If that load fails, it assumes that
<code>java.MyClass</code> is a package name, and no error is
reported:</p>
<pre>
js&gt; java.MyClass
[JavaPackage java.MyClass]
</pre>
<p>Only if you attempt to use this object as a class will an
error be reported.</p>
<h2>Working with Java objects</h2>
<p>Now that we can access Java classes, the next logical step is to
create an object. This works just as in Java, with the use of the
<code>new</code> operator:</p>
<pre>
js&gt; new java.util.Date()
Thu Jan 24 16:18:17 EST 2002
</pre>
<p>If we store the new object in a JavaScript variable, we can then
call methods on it:</p>
<pre>
js&gt; f = new java.io.File("test.txt")
test.txt
js&gt; f.exists()
true
js&gt; f.getName()
test.txt
</pre>
<p>Static methods and fields can be accessed from the class object
itself:</p>
<pre>
js&gt; java.lang.Math.PI
3.141592653589793
js&gt; java.lang.Math.cos(0)
1
</pre>
<p>In JavaScript, unlike Java, the method by itself is an
object and can be evaluated as well as being called. If we just view the method
object by itself we can see the various overloaded forms of the method:</p>
<pre>
js&gt; f.listFiles
function listFiles() {/*
java.io.File[] listFiles()
java.io.File[] listFiles(java.io.FilenameFilter)
java.io.File[] listFiles(java.io.FileFilter)
*/}
</pre>
<p>This output shows that the <code>File</code> class defines three
overloaded methods <code>listFiles</code>: one that takes no
arguments, another with a <code>FilenameFilter</code> argument, and a
third with a <code>FileFilter</code> argument. All the methods return
an array of <code>File</code> objects. Being able to view the
parameters and return type of Java methods is particularly useful in
exploratory programming where we might be investigating a method and
are unsure of the parameter or return types. </p>
<p>Another useful feature for exploratory programming is the ability
to see all the methods and fields defined for an object. Using the
JavaScript <code>for..in</code> construct, we can print out all these
values:</p>
<pre>
js&gt; for (i in f) { print(i) }
exists
parentFile
mkdir
toString
wait
<em>[44 others]</em>
</pre>
<p>Note that not only the methods of the <code>File</code> class are
listed, but also the methods inherited from the base class
<code>java.lang.Object</code> (like <code>wait</code>). This makes it
easier to work with objects in deeply nested inheritance hierarchies
since you can see all the methods that are available for that
object.</p>
<p>Rhino provides another convenience by allowing properties of
JavaBeans to be accessed directly by their property names. A JavaBean
property <code>foo</code> is defined by the methods
<code>getFoo</code> and <code>setFoo</code>. Additionally, a boolean
property of the same name can be defined by an <code>isFoo</code>
method <a href="#ref2">[2]</a>. For example, the following code
actually calls the <code>File</code> object's <code>getName</code> and
<code>isDirectory</code> methods.</p>
<pre>
js&gt; f.name
test.txt
js&gt; f.directory
false
</pre>
<h2>Calling overloaded methods</h2>
<p>The process of choosing a method to call based upon the types of
the arguments is called <em>overload resolution</em>. In Java,
overload resolution is performed at compile time, while in Rhino it
occurs at runtime. This difference is inevitable given JavaScript's
use of dynamic typing as was discussed in Chapter 2: since the type of
a variable is not known until runtime, only then can overload
resolution occur.</p>
<p>As an example, consider the following Java class that defines a
number of overloaded methods and calls them.</p>
<pre>
public class Overload {
public String f(Object o) { return "f(Object)"; }
public String f(String s) { return "f(String)"; }
public String f(int i) { return "f(int)"; }
public String g(String s, int i) { return "g(String,int)"; }
public String g(int i, String s) { return "g(int,String)"; }
public static void main(String[] args) {
Overload o = new Overload();
Object[] a = new Object[] { new Integer(3), "hi", Overload.class };
for (int i = 0; i != a.length; ++i)
System.out.println(o.f(a[i]));
}
}
</pre>
<p>When we compile and execute the program, it produces the output</p>
<pre>
f(Object)
f(Object)
f(Object)
</pre>
<p>However, if we write a similar script</p>
<pre>
var o = new Packages.Overload();
var a = [ 3, "hi", Packages.Overload ];
for (var i = 0; i != a.length; ++i)
print(o.f(a[i]));
</pre>
<p>and execute it, we get the output</p>
<pre>
f(int)
f(String)
f(Object)
</pre>
<p>Because Rhino selects an overloaded method at runtime, it calls the
more specific type that matches the argument. Meanwhile Java selects
the overloaded method purely on the type of the argument at compile
time. </p>
<p>Although this has the benefit of selecting a method that may be a
better match for each call, it does have an impact on performance
since more work is done at each call. In practice this performance
cost hasn't been noticeable in real applications.</p>
<p>Because overload resolution occurs at runtime, it can fail at
runtime. For example, if we call <code>Overload</code>'s method
<code>g</code> with two integers we get an error because neither form
of the method is closer to the argument types than the other:</p>
<pre>
js&gt; o.g(3,4)
js:"&lt;stdin&gt;", line 2: The choice of Java method Overload.g
matching JavaScript argument types (number,number) is ambiguous;
candidate methods are:
class java.lang.String g(java.lang.String,int)
class java.lang.String g(int,java.lang.String)
</pre>
<p>A more precise definition of overloading semantics can be
found at <a
href="http://www.mozilla.org/js/liveconnect/lc3_method_overloading.html">http://www.mozilla.org/js/liveconnect/lc3_method_overloading.html</a>.</p>
<h2>Implementing Java interfaces</h2>
<p>Now that we can access Java classes, create Java objects, and
access fields, methods, and properties of those objects, we have a
great deal of power at our fingertips. However, there are a few
instances where that is not enough: many APIs in Java work by
providing interfaces that clients must implement. One example of this
is the <code>Thread</code> class: its constructor takes a
<code>Runnable</code> that contains a single method <code>run</code>
that will be called when the new thread is started. </p>
<p>To address this need, Rhino provides the ability to create new Java
objects that implement interfaces. First we must define a JavaScript
object with function properties whose names match the methods required
by the Java interface. To implement a <code>Runnable</code>, we need
only define a single method <code>run</code> with no parameters. If
you remember from Chapter 3, it is possible to define a JavaScript
object with the <code>{propertyName: value}</code> notation. We can
use that syntax here in combination with a function expression to
define a JavaScript object with a <code>run</code> method:</p>
<pre>
js&gt; obj = { run: function () { print("\nrunning"); } }
[object Object]
js&gt; obj.run()
running
</pre>
<p>Now we can create an object implementing the <code>Runnable</code> interface
by constructing a <code>Runnable</code>:</p>
<pre>
js&gt; r = new java.lang.Runnable(obj);
[object JavaObject]
</pre>
<p>In Java it is not possible to use the <code>new</code> operator on
an interface because there is no implementation available. Here Rhino
gets the implementation from the JavaScript object
<code>obj</code>. Now that we have an object implementing
<code>Runnable</code>, we can create a <code>Thread</code> and run
it. The function we defined for <code>run </code>will be called on a
new thread.</p>
<pre>
js&gt; t = new java.lang.Thread(r)
Thread[Thread-2,5,main]
js&gt; t.start()
js&gt;
running
</pre>
<p>The final <code>js</code> prompt and the output from the new thread
may appear in either order, depending on thread scheduling.</p>
<p>Behind the scenes, Rhino generates the bytecode for a new Java
class that implements <code>Runnable</code> and forwards all calls to
its <code>run</code> method over to an associated JavaScript
object. The object that implements this class is called a <em>Java
adapter</em>. Because the forwarding to JavaScript occurs at runtime,
it is possible to delay defining the methods implementing an interface
until they are called. While omitting a required method is bad
practice for programming in the large, it's useful for small scripts
and for exploratory programming.</p>
<h2>The <code>JavaAdapter</code> constructor</h2>
<p>In the previous section we created Java adapters using the
<code>new</code> operator with Java interfaces. This approach has its
limitations: it's not possible to implement multiple interfaces, nor
can we extend non-abstract classes. For these reasons there is a
<code>JavaAdapter</code> constructor. </p>
<p>The syntax of the <code>JavaAdapter</code> constructor is</p>
<pre>
new JavaAdapter(javaIntfOrClass, [javaIntf, ..., javaIntf,] javascriptObject)
</pre>
<p>Here <code>javaIntfOrClass</code> is an interface to implement or a
class to extend and <code>javaIntf</code> are aditional interfaces to
implement. The <code>javascriptObject</code> is the JavaScript object
containing the methods that will be called from the Java adapter. </p>
<p>In practice there's little need to call the
<code>JavaAdapter</code> constructor directly. Most of the time the
previous syntaxes using the <code>new</code> operator will be
sufficient.</p>
<h2>JavaScript functions as Java interfaces</h2>
<p>Often we need to implement an interface with only one method, like in the
previous <code>Runnable</code> example or when providing various event
listener implementations. To facilitate this Rhino allows to pass
JavaScript function when such interface is expected. The
function is called as the implementation of interface method.</p>
<p>Here is the simplified <code>Runnable</code> example:</p>
<pre>
js&gt; t = java.lang.Thread(function () { print("\nrunning"); });
Thread[Thread-0,5,main]
js&gt; t.start()
js&gt;
running
</pre>
Rhino also allows to use JavaScript function as implementation of Java
interface with more then method if all the methods has the same
signature. When calling the function, Rhino passes method's name as
the additional argument. Function can
use it to distinguish on behalf of which method it was called:
<pre>
js&gt; var frame = new Packages.javax.swing.JFrame();
js&gt; frame.addWindowListener(function(event, methodName) {
if (methodName == "windowClosing") {
print("Calling System.exit()..."); java.lang.System.exit(0);
}
});
js&gt; frame.setSize(100, 100);
js&gt; frame.visible = true;
true
js&gt; Calling System.exit()...
</pre>
<h2>Creating Java arrays</h2>
<p>Rhino provides no special syntax for creating Java arrays. You
must use the <code>java.lang.reflect.Array</code> class for this
purpose. To create an array of five Java strings you would make the
following call:</p>
<pre>
js&gt; a = java.lang.reflect.Array.newInstance(java.lang.String, 5);
[Ljava.lang.String;@7ffe01
</pre>
<p>To create an array of primitive types, we must use the special TYPE
field defined in the associated object class in the
<code>java.lang</code> package. For example, to create an array of
bytes, we must use the special field
<code>java.lang.Byte.TYPE</code>:</p>
<pre>
js&gt; a = java.lang.reflect.Array.newInstance(java.lang.Character.TYPE, 2);
[C@7a84e4
</pre>
<p>The resulting value can then be used anywhere a Java array
of that type is allowed.</p>
<pre>
js&gt; a[0] = 104
104
js&gt; a[1] = 105
105
js&gt; new java.lang.String(a)
hi
</pre>
<h2>Java strings and JavaScript strings</h2>
<p>It's important to keep in mind that Java strings and JavaScript
strings are <strong>not</strong> the same. Java strings are instances
of the type <code>java.lang.String</code> and have all the methods
defined by that class. JavaScript strings have methods defined by
<code>String.prototype</code>. The most common stumbling block is
<code>length</code>, which is a method of Java strings and a dynamic
property of JavaScript strings:</p>
<pre>
js&gt; javaString = new java.lang.String("Java")
Java
js&gt; jsString = "JavaScript"
JavaScript
js&gt; javaString.length()
4
js&gt; jsString.length
10
</pre>
<p>Rhino provides some help in reducing the differences between the
two types. First, you can pass a JavaScript string to a Java method
that requires a Java string and Rhino will perform the conversion. We
actually saw this feature in action on the call to the
<code>java.lang.String</code> constructor in the preceding
example.</p>
<p>Rhino also makes the JavaScript methods available to Java strings
if the java.lang.String class doesn't already define them. For
example:</p>
<pre>
js&gt; javaString.match(/a.*/)
ava
</pre>

The ability to call Java from JavaScript was first implemented as part
of a Netscape browser technology called
<em>LiveConnect</em>. However, since that technology also
encompassed communication with browser plugins, and since the way of
calling JavaScript from Java in Rhino is entirely different, that term
won't be used in this paper.</p>

<title>Debugger API for Rhino</title>
</head>
<body bgcolor="#FFFFFF">
<h1><center>Debugger API for Rhino</center></h1>
<p>
<font color="red"><center>This release of the Debugger API should be considered to be of Beta quality.</center></font>
<p>
The Debugger API for Rhino consists of a set of Java interfaces
which describes a high level debugger API and a default implementation of that
API.
<p>
Most of the API is in the <code>com.netscape.javascript.debug</code> package. It is built
upon low-level support built into the core engine in <code>com.netscape.javascript</code>.
<p>
The <code>com.netscape.javascript.debug</code> package includes an implementation of the Debugger API
interfaces outlined below. The class <code>com.netscape.javascript.debug.DebugManager.java</code>
implements the <a href="com/netscape/javascript/debug/IDebugManager.html">IDebugManager</a>
interface and <code>com.netscape.javascript.debug.SourceTextManagerImpl.java</code> implements
the <a href="com/netscape/javascript/SourceTextManager.html">SourceTextManager</a> interface.
<p>
The class <code>com.netscape.javascript.tools.shell.Main.java</code> provides an
example which invokes the Debugger API.
<p>
<hr>
<p>
The core interface of the API is <a href="com/netscape/javascript/debug/IDebugManager.html">IDebugManager</a>.
This interface provide the central point for interacting with the debug system.
It supports the setting of the following hooks:
<ul>
<li><a href="com/netscape/javascript/debug/IInterruptHook.html">IInterruptHook</a> for immediate interrupt.
<li><a href="com/netscape/javascript/debug/IInstructionHook.html">IInstructionHook</a> for breakpoints.
<li><a href="com/netscape/javascript/debug/IDebugBreakHook.html">IDebugBreakHook</a> for breaking on errors.
<li><a href="com/netscape/javascript/debug/IErrorReporter.html">IErrorReporter</a> for hooking into the error reporter system.
<li><a href="com/netscape/javascript/debug/IScriptHook.html">IScriptHook</a> for notification of script and function load and unload.
</ul>
Customers of the Debugger API can provide implementations of these hook
interfaces which can be passed to the <i>IDebugManager</i> in order receive
notification of the various events within the core JavaScript engine.
<p>
When hooks are called they are passed appropriate objects which are implemented
by the Debugger API to describe such things as <i>stack frames</i>,
<i> program counter locations</i>, etc. The interfaces for these objects are:
<ul>
<li><a href="com/netscape/javascript/debug/IThreadState.html">IThreadState</a> representing the state of the stopped thread.
<li><a href="com/netscape/javascript/debug/IStackFrame.html">IStackFrame</a> representing a stack frame.
<li><a href="com/netscape/javascript/debug/IPC.html">IPC</a> representing a program counter location.
<li><a href="com/netscape/javascript/debug/IScript.html">IScript</a> representing a compiled JavaScript script or function.
<li><a href="com/netscape/javascript/debug/ISourceLocation.html">ISourceLocation</a> representing a location in the souce code.
</ul>
<p>
<hr>
<p>
<a href="com/netscape/javascript/SourceTextManager.html">SourceTextManager</a>
is an interface used to supply a centralized location from which a debugger
client can access JavaScript source. It supports capturing source as it is
parsed by <i>Rhino</i>. Alternately, source can be fed to it by the
embedding; e.g. in a browser embedding where the JavaScript code is just a
part of the html source the browser can feed the entire source to the
<i>SourceTextManager</i> so that a debugger can 'see' the whole source and
not just the part that is fed to the JavaScript compiler.
<p>
<a href="com/netscape/javascript/SourceTextItem.html">SourceTextItem</a> is an
interface representing a single 'block' of source code text (typically this
is an entire source file). This may be pure JavaScript source, or may include
JavaScript source embedded in html or whatever. The point is that this is the
text that a debugger should show to a user while debugging the JavaScript code.
This interface supports incrementally updated content. This is specifically
useful in browser embeddings where text is received in blocks. In fact, in a
browser it is possible that some of the source on a page may be compiled
and run even before the entire content of the page has been received from a
server.
<p>
<hr>
<p>
<a href="com/netscape/javascript/debug/ILaunchableDebugger.html">ILaunchableDebugger</a>
is an interface that abstractly represents a debugger user interface. It is
defined to allow an embedding to request that a debugger be launched without
requiring that the embedding be coupled at compile time to a particular debugger
implementation.
<p>
<hr>
<h3>Limitations and unimplemented features</h3>
<ul>
<li>Data Watchpoints are not implemented.
<li>Catching exceptions thrown in JavaScript code is not implemented.
<li>Per context hooking is not implemented.
<li>Setting the debug level to any non-zero value forces the optimization level to zero.
<li>Tracking of calls to plain Java methods from JavaScript is not implemented.
<li>Running at debug level >= 6 causes JIT errors with the Symantec JVM (but no other JVMs)
<li>The Debug API has not been rigorously tested.
</ul>

<h1>
Small Footprint</h1></center>
A few changes can be made to reduce the footprint of Rhino for embeddings
where space is at a premium. On a recent build, Rhino consumed 355,883
bytes of space for uncompressed class files. With various changes that
number can be reduced to 281,455 bytes.
<br>&nbsp;
<h3>
Tools</h3>
Most embeddings won't need any of the classes in <tt>org.mozilla.javascript.tools</tt>
or any of its subpackages.
<br>&nbsp;
<h3>
Regular Expressions</h3>
The package <tt>org.mozilla.javascript.regexp</tt> can be removed. Rhino
will continue to run, although it will not be able to execute any regular
expression matches. This change saves 37,792 bytes of class files.
<br>&nbsp;
<h3>
JavaAdapter</h3>
Implementing the JavaAdapter functionality requires the ability to generate
classes on the fly. Removing <tt>org.mozilla.javascript.JavaAdapter</tt> and all
the classes in package <tt>org.mozilla.classfile</tt> will disable this
functionality, but Rhino will otherwise run correctly. These changes save
36,636 bytes.
<br>&nbsp;
where space is at a premium. On a recent build, the length of js.jar was 603,127 bytes corresponding to 1,171,708 bytes of all uncompressed Rhino classes with debug information included.
With various changes js.jar size can be reduced to 204,689 bytes corresponding to 424,774 bytes of uncompressed classes.
<h3>Tools</h3>
<p>
Most embeddings won't need any of the classes in <tt>org.mozilla.javascript.tools</tt> or any of its sub-packages.
<h3>
Optimizer</h3>
<p>
It is possible to run Rhino with interpreter mode only, allowing you to remove
classes for classfile generation. Remove the classes in packages
<tt>org.mozilla.classfile</tt> and <tt>org.mozilla.javascript.optimizer</tt>.
<br>&nbsp;
code for classfile generation that include all the classes from
<tt>org.mozilla.javascript.optimizer</tt> package.
<h3>JavaAdapter</h3>
<p>
Implementing the JavaAdapter functionality requires the ability to generate
classes on the fly. Removing <tt>org.mozilla.javascript.JavaAdapter</tt> will disable this functionality, but Rhino will otherwise run correctly.
<h3>Class generation library</h3>
<p>
If you do not include Optimizer or JavaAdapter, nor do you use PolicySecurityController then you do not need Rhino library for class file generation and you can remove all the classes from in <tt>org.mozilla.classfile</tt> package.
<h3>Regular Expressions</h3>
<p>
The package <tt>org.mozilla.javascript.regexp</tt> can be removed. Rhino
will continue to run, although it will not be able to execute any regular
expression matches. This change saves 47,984 bytes of class files.
<h3>Debug information</h3>
<p>
Debug information in Rhino classes consumes about 25% of code size and if you can live without that, you can recompile Rhino to remove it.
<h2>smalljs.jar</h2>
<p>
Ant build script in Rhino supports smalljar target that will generate
smalljs.jar that does not include Tools, Optimizer, JavaAdapter and Class
generation library, Regular Expressions, E4X implementataion and deprecated
files. To build such minimalist jar without debug information, run the
following command from the top directory of Rhino distribution:
<pre>
ant clean
ant -Ddebug=off -Dno-regexp=true -Dno-e4x=true smalljar
</pre>
If you omit <tt>-Dno-regexp=true</tt>, then the resulting smalljs.jar will
include Regular Expression support. Similarly omitting <tt>-Dno-e4x=true</tt>
results in smalljs.jar that includes runtime support for E4X.

example, accessing

Security</h3>
The security features in Rhino provide the ability to track the origin

<h2><a name="security" id="security">Security</a></h2>
<p>The security features in Rhino provide the ability to track the origin
of a piece of code (and any pieces of code that it may in turn generate).
These features allow for the implementation of a traditional URL-based
security policy for JavaScript as in Netscape Navigator. Embeddings that
trust the JavaScript code they execute may ignore the security features.
trust the JavaScript code they execute may ignore the security features.</p>
<p>Embeddings that run untrusted JavaScript code must do two things to
enable the security features. First, every <tt>Context</tt> that is created
must be supplied an instance of an object that implements the <tt>SecuritySupport</tt>
interface. This will provide Rhino the support functionality it needs to
perform security-related tasks.
<p>Second, the value of the property <tt>security.requireSecurityDomain</tt>
should be changed to <tt>true</tt> in the resource bundle <tt>org.mozilla.javascript.resources.Security</tt>.

created must be supplied an instance of an object that implements the
<tt>SecuritySupport</tt> interface. This will provide Rhino the support
functionality it needs to perform security-related tasks.</p>
<p>Second, the value of the property
<code class="filename">security.requireSecurityDomain</code>
should be changed to <var>true</var> in the resource bundle <code class="filename">org.mozilla.javascript.resources.Security</code>.
The value of this property can be determined at runtime by calling the
<tt>isSecurityDomainRequired</tt>
method of <tt>Context</tt>. Setting this property to true requires that
<code>isSecurityDomainRequired</code>
method of <code>Context</code>. Setting this property to true requires that
any calls that compile or evaluate JavaScript must supply a security domain
object of any object type that will be used to identify JavaScript code.
In a typical client embedding, this object might be a string with the URL
of the server that supplied the script, or an object that contains a representation
of the signers of a piece of code for certificate-based security policies.

can be retrieved in the following manner. The class context should be
obtained from the security manager (see <code class="command">java.lang.SecurityManager.getClassContext()</code>).
Then, the class of the code that called to request the restricted action
can be obtained by looking an appropriate index into the class context
array. If the caller is JavaScript the class obtained may be one of two
types. First, it may be the class of the interpreter if interpretive mode
is in effect. Second, it may be a generated class if classfile generation
is supported. An embedding can distinguish the two cases by calling <tt>isInterpreterClass()</tt>
in the <tt>Context</tt> class. If it is the interpreter class, call the
getInterpreterSecurityDomain() method of Context to obtain the security
domain of the currently executing interpreted script or function. Otherwise,
it must be a generated class, and an embedding can call <tt>getSecurityDomain()</tt>
in the class implementing
<tt>SecuritySupport</tt>. When the class was
is supported. An embedding can distinguish the two cases by calling
<code class="command">isInterpreterClass()</code>
in the <code class="filename">Context</code> class. If it is the
interpreter class, call the getInterpreterSecurityDomain() method of
Context to obtain the security domain of the currently executing
interpreted script or function. Otherwise, it must be a generated class,
and an embedding can call <code class="command">getSecurityDomain()</code>
in the class implementing <code>SecuritySupport</code>. When the class was
defined and loaded, the appropriate security domain was associated with
it, and can be retrieved by calling this method. Once the security domain
has been determined, an embedding can perform whatever checks are appropriate
to determine whether access should be allowed.

<h1 style="text-align: center;">Performance Hints</h1>
<h3><a name="varstatements" id="varstatements"><code>var</code> Statements</a></h3>
<p>Use <code>var</code> statements when possible. Not only is it good
programming practice, it can speed up your code by allowing the compiler
to generate special code to access the variables. For example, you could
rewrite</p>
<pre class="code">
function sum(a) {
result = 0;
for (i=0; i &lt; a.length; i++)
result += a[i];
return result;
}
</pre>
<p>as</p>
<pre class="code">
function sum(a) {
var result = 0;
for (var i=0; i &lt; a.length; i++)
result += a[i];
return result;
}
</pre>
<center>
<h1>
Performance Hints</h1></center>&nbsp;
<h3>
<tt>var</tt> Statements</h3>Use <tt>var</tt> statements when possible. Not only is it good
programming practice, it can speed up your code by allowing the compiler to
generate special code to access the variables. For example, you could rewrite
<p><tt>function sum(a) {</tt>
<br><tt>&nbsp;&nbsp;&nbsp; result = 0;</tt>
<br><tt>&nbsp;&nbsp;&nbsp; for (i=0; i &lt;
a.length; i++)</tt>
<br><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; result += a[i];</tt>
<br><tt>&nbsp;&nbsp;&nbsp; return result;</tt>
<br><tt>}</tt>
<p>as
<p><tt>function sum(a) {</tt>
<br><tt>&nbsp;&nbsp;&nbsp; var result = 0;</tt>
<br><tt>&nbsp;&nbsp;&nbsp; for (var i=0; i
&lt; a.length; i++)</tt>
<br><tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; result += a[i];</tt>
<br><tt>&nbsp;&nbsp;&nbsp; return result;</tt>
<br><tt>}</tt>
<p>This is not equivalent code because the second version does
not modify global variables <tt>result</tt> and <tt>i</tt>. However, if you don't intend for any other function to
access these variables, then storing them globally is probably wrong anyway
(what if you called another function that had a loop like the one in <tt>sum</tt>!).
<br>&nbsp;
<h3>
Arrays</h3>Use the forms of the Array constructor that
specify a size or take a list of initial elements. For example, the code
<p><tt>var a = new Array();</tt>
<br><tt>for (var i=0; i &lt; n; i++)</tt>
<br><tt>&nbsp;&nbsp;&nbsp; a[i] = i;</tt>
<p>could be sped up by changing the constructor call to <tt>new Array(n)</tt>. A constructor call like that indicates to
the runtime that a Java array should be used for the first <i>n</i> entries of the array. Similarly,
<tt>new
Array(&quot;a&quot;, &quot;b&quot;, &quot;c&quot;)</tt> or <tt>[&quot;a&quot;, &quot;b&quot;, &quot;c&quot;]</tt> will cause a 3-element
Java array to be allocated to hold the contents of the JavaScript array.
<br>&nbsp;
<br>&nbsp;
<h3>
<tt>eval</tt> and <tt>new Function</tt></h3>Avoid calling <tt>eval</tt> when
possible. Calls to <tt>eval</tt> are slow because the script
being executed must be compiled. Constructing a new function object can be slow
for the same reason, while function expressions are more efficient because the
function can be compiled. For example, the code
<p><tt>function MyObject(a) {</tt>
<br><tt>&nbsp;&nbsp;&nbsp; this.s = a;</tt>
<br><tt>&nbsp;&nbsp;&nbsp; this.toString = new
Function(&quot;return this.s&quot;);</tt>
<br><tt>}</tt>
<p>could be written more efficiently as
<p><tt>function MyObject(a) {</tt>
<br><tt>&nbsp;&nbsp;&nbsp; this.s = a;</tt>
<br><tt>&nbsp;&nbsp;&nbsp; this.toString =
function () { return this.s }</tt>
<br><tt>}</tt>
<p>Beginning with Rhino 1.4 Release 2, code
passed to eval and new Function will be interpreted rather than compiled to
class files.
<br>&nbsp;</p>
<h3>
with</h3>Using the <tt>with</tt>
statement prevents the compiler from generating code for fast access to local
variables. You're probably better off explicitly accessing any properties of the
object.
<br>&nbsp;
<p>
<hr WIDTH="100%">
<br><a href="index.html">back to top</a>

not modify global variables <code>result</code> and <code>i</code>.
However, if you don't intend for any other function to access these
variables, then storing them globally is probably wrong anyway
(what if you called another function that had a loop like the one
in <code>sum</code>!).</p>
<h3><a name="arrays" id="arrays">Arrays</a></h3>

take a list of initial elements. For example, the code</p>
<pre class="code">
var a = new Array();

<code>new Array(n)</code>. A constructor call like that indicates
to the runtime that a Java array should be used for the first
<var>n</var> entries of the array. Similarly,<br><br>
<code>new Array(&quot;a&quot;, &quot;b&quot;, &quot;c&quot;)</code><br>
or<br>
<code>[&quot;a&quot;, &quot;b&quot;, &quot;c&quot;]</code><br><br>
will cause a 3-element Java array to be allocated to hold the

<h2 align="center">Debug API changes in Rhino 1.5 Release 4</h2>
<p>
The main difference between the old and new API is that the application needs to implement both org.mozilla.javascript.debugger.Debugger and
org.mozilla.javascript.debugger.DebugFrame interfaces to receive debug
information during script execution. See the API documentation for these
classes for details:
<br>
<tt><a href="http://lxr.mozilla.org/mozilla/source/js/rhino/src/org/mozilla/javascript/debug/DebugFrame.java">http://lxr.mozilla.org/mozilla/source/js/rhino/src/org/mozilla/javascript/debug/DebugFrame.java</a>
<br><a href="http://lxr.mozilla.org/mozilla/source/js/rhino/src/org/mozilla/javascript/debug/Debugger.java">http://lxr.mozilla.org/mozilla/source/js/rhino/src/org/mozilla/javascript/debug/Debugger.java</a>
</tt>
<p>
In addition the org.mozilla.javascript.debugger.DebuggableEngine interface and the getDebuggableEngine method in org.mozilla.javascript.Context are replaced by 3 Context methods: setDebugger, getDebugger and getDebuggerContextData to set/get debugger and its Context data in the current thread Context:<br>
<tt><a href="http://lxr.mozilla.org/mozilla/source/js/rhino/src/org/mozilla/javascript/Context.java">http://lxr.mozilla.org/mozilla/source/js/rhino/src/org/mozilla/javascript/Context.java</a></tt>
<p>The following gives few examples how to update your current application to the new API.
<p>
1. Setting and querying a Debugger implementation
<p>
Old API:
<pre>
cx.getDebuggableEngine.setDebugger(debugger);
cx.getDebuggableEngine.getDebugger();
</pre>
New API:
<pre>
cx.setDebugger(debugger);
cx.getDebugger();
</pre>
<p>
2. Monitoring execution of each line in the script
<p>
Old implementation:
<pre>
public MyDebugger implement Debugger {
public void handleCompilationDone(Context cx,
DebuggableScript fnOrScript,
StringBuffer source)
{
}
void handleBreakpointHit(Context cx)
{
DebugFrame frame = cx.getDebuggableEngine().getFrame(0);
System.out.println("New line:" + frame.getLineNumber());
}
void handleExceptionThrown(Context cx, Object exception)
{
}
}
...
cx.getDebuggableEngine.setDebugger(new MyDebugger());
cx.getDebuggableEngine.setBreakNextLine(true);
</pre>
New implementation:
<pre>
public MyDebugger implement Debugger
{
public void handleCompilationDone(Context cx,
DebuggableScript fnOrScript,
StringBuffer source)
{
}
public DebugFrame getFrame(Context cx, DebuggableScript fnOrScript)
{
return new MyDebugFrame();
}
}
class MyDebugFrame implements DebugFrame
{
public void onEnter(Context cx, Scriptable activation,
Scriptable thisObj, Object[] args)
{
}
public void onExceptionThrown(Context cx, Throwable ex)
{
}
public void onExit(Context cx, boolean byThrow,
Object resultOrException)
{
}
public void onLineChange(Context cx, int lineNumber)
{
System.out.println("New line:" + frame.getLineNumber());
}
}
...
cx.setDebugger(new MyDebugger());
</pre>
Note the in the new implementation the application can monitor function enter/exit by customizing enterFrame and onExit in the above code.
<p>
3. Breakpoint handling
<p>
Old implementation:
<pre>
public MyDebugger implement Debugger {
public void handleCompilationDone(Context cx, DebuggableScript fnOrScript,
StringBuffer source)
{
int breakpointLine = ...;
fnOrScript.placeBreakpoint(breakpointLine);
}
void handleBreakpointHit(Context cx) {
DebugFrame frame = cx.getDebuggableEngine().getFrame(0);
System.out.println("Breakpoint hit: "+frame.getSourceName()+":"+frame.getLineNumber());
}
void handleExceptionThrown(Context cx, Object exception)
{
}
}
...
cx.getDebuggableEngine.setDebugger(new MyDebugger());
</pre>
New implementation:
<pre>
public MyDebugger implement Debugger
{
public void handleCompilationDone(Context cx,
DebuggableScript fnOrScript,
StringBuffer source)
{
}
public DebugFrame getFrame(Context cx, DebuggableScript fnOrScript)
{
return new MyDebugFrame(fnOrScript);
}
}
class MyDebugFrame implements DebugFrame
{
DebuggableScript fnOrScript;
MyDebugFrame(DebuggableScript fnOrScript)
{
this.fnOrScript = fnOrScript;
}
public void onEnter(Context cx, Scriptable activation,
Scriptable thisObj, Object[] args)
{
System.out.println("Frame entered");
}
public void onLineChange(Context cx, int lineNumber)
{
if (isBreakpoint(lineNumber)) {
System.out.println("Breakpoint hit: "+fnOrScript.getSourceName()+":"+lineNumber);
}
}
public void onExceptionThrown(Context cx, Throwable ex)
{
}
public void onExit(Context cx, boolean byThrow,
Object resultOrException)
{
System.out.println("Frame exit, result="+resultOrException);
}
private boolean isBreakpoint(int lineNumber)
{
...
}
}
...
cx.setDebugger(new MyDebugger());
</pre>
Here debugger during execution needs to decide if a particular line has breakpoint on it set or not during script execution, not at the moment of script initialization.
<p>See also Rhino Debugger that fully explore the new API:<br><tt><a href="http://lxr.mozilla.org/mozilla/source/js/rhino/toolsrc/org/mozilla/javascript/tools/debugger/Main.java">http://lxr.mozilla.org/mozilla/source/js/rhino/toolsrc/org/mozilla/javascript/tools/debugger/Main.java</a></tt>. The debugger changes includes support for debugging eval and Function scripts and loading script sources from their URL if debugger was not installed during scripts initialization.

Rhino Change Log</h1>
This is a log of changes since the release of Rhino 1.5 Release 3.
<h3>Rhino debug API changes</h3>
A new, incompatible Rhino debug API gives an option to monitor
entering/leaving of script functions while decreasing the amount of code to
implement the API in the Rhino core. Details are available <a href="rhino15R4-debugger.html">here</a>. With the new API <a href="debugger.html">Rhino Debugger</a> provides options to break on function enter/exit, can debug scripts defined by eval and Function construction and scripts loaded prior the debugger were started.
<h3>WrapFactory introduced, WrapHandler deprecated</h3>
A design flaw in the WrapHandler interface (a call to a Java contructor from
JavaScript would result in a call to wrap the result, which would then be
cast to a Scriptable) inspired the deprecation of that interface and the
introduction of a new class, WrapFactory, that contains a new method called
on the result of a constructor call and can be customized by application if necessary.
<p>
In addition, WrapFactory has the new <tt>setJavaPrimitiveWrap</tt> method to control if instances of Java <tt>String</tt> and <tt>Number</tt> class should be wrapped to special script objects as any other Java objects so a script can access any method <tt>String</tt> and <tt>Number</tt>, or they should be converted to JavaScript primitive strings and numbers.
<h3>New security interfaces</h3>
<p>
Igor Bukanov contributed a new security implementation that allows integration with Java2 security model and prevents scripts to escape the security sandbox via eval/Function schemes.
<p>
Due to this changes SecuritySupport interface is replaced by ClassShutter and SecurityController, where ClassShutter controls which classes are visible to scripts via LiveConnect and SecurityController provides permission management. For compatibility SecuritySupport is still available as a deprecated interface but only its visibleToScripts method is used as an alias for ClassShutter.visibleToScripts. See API documentation for new classes for details.
<p>
An implementation of SecurityController that uses java policy settings to restrict script permissions based on its URL is available with Rhino shell. See the <a href="http://lxr.mozilla.org/mozilla/source/js/rhino/toolsrc/org/mozilla/javascript/tools/shell/JavaPolicySecurity.java">JavaPolicySecurity</a> source for details. To activate it, set the <tt>rhino.use_java_policy_security</tt> system property to true when invoking Rhino shell together with installing a security manager.
<h3>Serialization chages</h3>
Due to changes in Rhino implementation and bug fixes in serialization support runtime data serialized in Rhino 1.5 Release 3 can not be read back in the Release 4.
<h3>Regular expressions improvements</h3>
Roger Lawrence provided new regular expressions implementation which fully confirms to EcmaScript 262 standard and faster.
<h3>Scripting of classes from any class loader</h3>
Christopher Oliver contributed code to allow to use the <tt>Packages</tt> object as a constructor taking a class loader argument so a script can access classes defined by that class loader. For example, to access classes from foo.jar file in the current directory, the following can be used:
<pre>
// create class loader
var loader = new java.net.URLClassLoader([new java.net.URL("file:./foo.jar")]);
// create its LiveConnect wrapper
var fooJar = new Packages(loader);
// create an instance of the class For from foo.jar
var obj = new fooJar.Foo(1, 2, 3);
obj.someMethod();
</pre>
<h3>Shell function to run external processes.</h3>
A new <tt>runCommand</tt> function is added to <a href="shell.html">Rhino Shell</a> to run external priocesses. For details, see JavaDoc for <a href="http://lxr.mozilla.org/mozilla/source/js/rhino/toolsrc/org/mozilla/javascript/tools/shell/Global.java">org.mozilla.javascript.tools.shell.Global#runCommand</a>.

<h1 align="center">Rhino 1.5 Release 4.1 Change Log</h1>
1.5R4.1 is a bug fix release to address mostly regressions from 1.5R3 found in 1.5R4. The only visible API change compared with 1.5R4 is two new methods in <tt>org.mozilla.javascript.Context</tt>, <tt>getApplicationClassLoader()</tt> and <tt>setApplicationClassLoader(ClasssLoader)</tt>. They allow to control the class loader Rhino uses when accessing application classes.

Rhino 1.5R5 Change Log</h1>
This is a log of significant changes in Rhino 1.5 Release 5.
<h3>Wrapping of JavaScript functions as Java interfaces</h3>
<p>
Rhino allows to pass a JavaScript function to a Java method expecting an interface which either has a single method or all its methods have the same number of parameters and each corresponding parameter has the same type.
The JavaScript function will be called whenever interface's method is called from Java. The function will receive all Java arguments properly converted into JS types and as the last parameter Rhino will pass interface method's name.
</p>
<p>
The feature allows to simplify code that previously had to create explicit JavaAdapter objects. For example, one can write now:
<pre>
var button = new javax.swing.JButton("My Button");
button.addActionListener(function(e) {
java.lang.System.out.println("Button click:"+e);
});
var frame = new javax.swing.JFrame("My Frame");
frame.addWindowListener(function(e, methodName) {
java.lang.System.out.println("Window event:"+e);
if (methodName == "windowClosing") {
java.lang.System.exit(0);
}
});
</pre>
instead of
<pre>
var button = new javax.swing.JButton("My Button");
button.addActionListener(new java.awt.event.WindowListener({
windowClosing : function(e) {
java.lang.System.out.println("Window event:"+e);
java.lang.System.exit(0);
},
windowActivated : function(e) {
java.lang.System.out.println("Window event:"+e);
},
// similar code for the rest of WindowListener methods
});
var frame = new javax.swing.JFrame("My Frame");
frame.addWindowListener(function(e, methodName) {
</pre>
which was necessary in the previous version of Rhino.
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=223435">Bugzilla 223435</a>.
</p>
<h3>uneval() and toSource()</h3>
<p>
Rhino fully supports <tt>uneval()</tt> function and <tt>toSource()</tt> method which are extensions to ECMAScript available in <a href="http://www.mozilla.org/js/">SpiderMonkey</a>. They return a string that can be passed to the <tt>eval()</tt> function to reconstruct the original value when possible. It is guaranteed that <tt>uneval(eval(uneval(x)))&nbsp;==&nbsp;uneval(x)</tt> and in many cases more useful notion <tt>eval(uneval(x))&nbsp;==&nbsp;deep_copy_of_x</tt> holds.
</p>
<p>
For example, here is an extract from a <a href="shell.html">Rhino shell</a> session:
</p>
<pre>
js&gt; var x = { a: 1, b: 2, c: [1,2,3,4,5], f: function test() { return 1; }, o: { property1: "Test", proeprty2: new Date()}}
js&gt; uneval(x)
({c:[1, 2, 3, 4, 5], o:{property1:"Test", proeprty2:(new Date(1076585338601))}, f:(function test() {return 1;}), a:1, b:2})
js&gt; x.toSource()
({c:[1, 2, 3, 4, 5], o:{property1:"Test", proeprty2:(new Date(1076585338601))}, f:(function test() {return 1;}), a:1, b:2})
js&gt; uneval(x.propertyThatDoesNotExist)
undefined
</pre>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=225465">Bugzilla 225465</a>.
</p>
<h3>seal() and changes in semantic of sealed objects</h3>
<p>
Rhino supports <tt>seal(object)</tt> function which is another ECMAScript extension from SpiderMonkey. The function makes the object immune to changes and any attempt to add, modify or delete a property of such object will throw an exception. Previously sealing was only possible through the Java <tt>sealObject()</tt> method in <tt>org.mozilla.javascript.ScriptableObject</tt> and before Rhino 1.5R5 it was possible to modify existing properties of sealed objects.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=203013">Bugzilla 203013</a>.
</p>
<h3>Exception changes</h3>
<p>
In Rhino 1.5R5 all exceptions generated during execution of a script provide information about script's source name and line number that triggered the exception. The exception class <tt>org.mozilla.javascript.JavaScriptException</tt> is used now only to represent exceptions explicitly thrown by the JavaScript <b>throw</b> statement, it never wraps exceptions thrown in a Java method invoked by the script. Such exceptions are always wrapped as <tt>org.mozilla.javascript.WrappedException</tt>.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=217584">Bugzilla 217584</a>, <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=219055">Bugzilla 219055</a>
and <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=225817">Bugzilla 225817</a>
</p>
<h3>Compiled scripts are scope independent</h3>
<p>
Previously Rhino required a scope object in the <tt>compileReader</tt> method of <tt>org.mozilla.javascript.Context</tt> to compile a script into <tt>org.mozilla.javascript.Script</tt> instances. Under some circumstances it was possible that the scope object would be stored in the compiled form of the script. It made impossible in such cases to reuse of the compiled form to execute the script against different scopes and lead to potential memory leaks.
<p>
</p>Rhino 1.5R5 fixes such misbehavior and <tt>compileReader</tt> and newly introduced <tt>compileString</tt> no longer take the scope argument. For compatibility the old form of <tt>compileReader</tt> is kept as a deprecated method.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=218440">Bugzilla 218440</a>.
</p>
<h3>Callable interface</h3>
<p>
All <tt>org.mozilla.javascript.Script</tt> and <tt>org.mozilla.javascript.Function</tt> instances in Rhino now implement the new interface <tt>org.mozilla.javascript.Callable</tt> which together with the new <tt>call</tt> method in <tt>org.mozilla.javascript.Context</tt> gives a simple way to call scripts and functions without explicit calls to <tt>Context.enter()</tt> and <tt>Context.exit()</tt>.
</p>
<p>
The <tt>Callable</tt> interface allows to set the value of JavaScript <b>this</b> during script execution to arbitrary <tt>org.mozilla.javascript.Scriptable</tt> instance overriding default bahaviour of using the scope object for the value of <b>this</b>.
</p>
<p>Rhino interpreter uses <tt>Callable</tt> to pass references to scripts and functions to <tt>org.mozilla.javascript.SecurityController</tt> directly without wrapping script code into an additional proxy <tt>Script</tt> object. It allows to optimize an implementation of <tt>callWithDomain</tt> method in <tt>org.mozilla.javascript.SecurityController</tt>.
</p>
<p>
For compatibility applications extending the previous version of <tt>SecurityController</tt> are fully supported but the new applications should override <tt>callWithDomain</tt> method, not <tt>execWithDomain</tt>.
</p>
<h3>No static caching</h3>
<p>
Rhino no longer caches generated classes and information about reflected Java classes in static objects. Instead such caches are stored in a top scope object and initialized by default during call to <tt>initStandardObjects</tt> of <tt>org.mozilla.javascript.Context</tt>. This can be overridden with the explicit call to the <tt>associate</tt> method of <tt>org.mozilla.javascript.ClassCache</tt> if cache sharing is desired.
</p>
<p>The cached objects no longer holds references to scope objects so even an application using multiple calls to <tt>Context.initStandardObjects</tt> and single shared <tt>ClassCache</tt> instance would not leak references to runtime library instantiations as it was the case with the previous Rhino for all applications.
</p>
The change allows to instantiate multiple Rhino runtime instances which would not interfere with each other and prevents memory leaks through ever growing caches. </p>
<h3>API for compiling scripts into class files</h3>
<p>The new class <tt>org.mozilla.javascript.optimizer.ClassCompiler</tt> provides a simple API to compile JavaScript source into set of Java class files with the given set of compilation options. <a href="jsc.html">JavaScript Compiler</a> was upgraded to use new API and the old API were deprecated.
</p>
<h3>API for Context sealing</h3>
<p>The new methods <tt>seal(Object)</tt>, <tt>unseal(Object)</tt> and <tt>isSealed()</tt> in <tt>org.mozilla.javascript.Context</tt> allows to make <tt>Context</tt> instances immune from changes. Rhino embeddings that needs to run potentially untrusted scripts may use the new functionality to proprly implement the sandbox for such scripts without too restrictive <tt>org.mozilla.javascript.ClassShutter</tt> implementation.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=236117">Bugzilla 236117</a>.
</p>
<h3>Optimizer generates only one class per script </h3>
<p>
In Rhino 1.5R5 the default optimization mode generates only one Java class for script and all its functions while previously the optimizer generated additional class for each function definition in the script. It improves loading time for scripts and decreases memory usage especially for scripts with many function definitions.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=198086">Bugzilla 198086</a>.
</p>
<h3>Improved support for huge scripts</h3>
<p>
The interpreted mode contains significantly less restrictions on size and complexity of the scripts and if the remaining restrictions are not satisfied, Rhino will report an exception instead of generating corrupted internal byte code for interpreting.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=225831">Bugzilla 225831</a>.

Change Log for Rhino</h1>
<h2>Rhino 1.6R1, released 2004-11-29</h2>
<h3>Release overview</h3>
<p>
Rhino 1.6R1 is the new major release of Rhino. It supports ECMAScript for XML (E4X) as specified by <a href="http://www.ecma-international.org/publications/standards/Ecma-357.htm">ECMA 357</a> standard. E4X is a set of language extensions adding native XML support for JavaScript without affecting the existing code base. <a href="http://lxr.mozilla.org/mozilla/source/js/rhino/examples/E4X/e4x_example.js">E4X example</a> demonstrates various E4X constructions and their usage in JavaScript code.
</p>
<p>
This version of Rhino should be binary compatible with the current embeddings that use only public <a href="apidocs/index.html">API</a> unless the code use the previously deprected classes as documented <a href="#Rhino1.5R1-deprecation-removal">below</a>. Please report any incompatibility issues to <a href="http://bugzilla.mozilla.org/enter_bug.cgi?product=Rhino">Bugzilla</a>.
</p>
</h3>
<a NAME="E4X"></a>
<h3>E4X implementation</h3>
<p>
The E4X code was donated to the Rhino project by <a href="http://www.bea.com/">BEA</a> and developed by staff from <a href="http://www.bea.com/">BEA</a> and <a href="http://www.agiledelta.com/">AgileDelta</a>.
</p>
<p>
It uses <a href="http://xmlbeans.apache.org/">XMLBeans</a> library to implement E4X runtime. The implementation was tested against versions 1.0.2 and 1.0.3 of XMLBeans. Please make sure that <tt>xbean.jar</tt> is avaialble on the classpath if you use E4X in your scripts.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=242805">Bugzilla 242805</a> for details. See also <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=270779">Bugzilla 270779</a>
for the list of known issues with E4X implementation in Rhino 1.6R1.
</p>
<h3>Other changes</h3>
<h4>Common root for Rhino execeptions</h4>
<p>
Now all Rhino execption classes are derived from <a href="apidocs/org/mozilla/javascript/RhinoException.html"><tt>org.mozilla.javascript.RhinoException</tt></a> which extends <tt>java.lang.RuntimeException</tt>.
The class gives the uniform way to access information about the script origin of the exception and simplifies execption handling in Rhino embeddings.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=244492">Bugzilla 244492</a> for details.
</p>
<h4>Removal of code complexity limits in the interpreter</h4>
<p>
The interpreter mode in Rhino does not limit any longer the script size or code complexity. It should be possible to execute any script as long as JVM resources allow so.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=244014">Bugzilla 244014</a> and <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=256339">Bugzilla 256339</a> for details.
</p>
<h4>Tail call elimination in the interpreter</h4>
<p>
The interpreter mode in Rhino implements tail call elimination to avoid excessive stack space consumption when a function returns result of a call to another function.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=257128">Bugzilla 257128</a>.
</p>
<h4>Support for continuations in the interpreter</h4>
<p>
The interpreter mode in Rhino supports continuations. The code is based on the ideas from the original implementation of continuations by Christopher Oliver and
<a href="http://sisc.sourceforge.net/">SISC</a> project. To use the
continuations make sure that the interpreter mode is selected through <a
href="apidocs/org/mozilla/javascript/Context.html#setOptimizationLevel(int)">setting</a>
the optimization level to -1 or by adding <tt>-opt -1</tt> to the command line
of <a href="shell.html">Rhino shell</a>.
</p>
<p>
Please note that the details of implementation and Java and JavaScript API for continuations may change in future in incompatible way.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=258844">Bugzilla 258844</a>.
</p>
<h4>JavaImporter constructor</h4>
<p>
<tt>JavaImporter</tt> is a new global constructor that allows to omit explicit package names when scripting Java:
</p>
<pre>
var SwingGui = JavaImporter(Packages.javax.swing,
Packages.javax.swing.event,
Packages.javax.swing.border,
java.awt.event,
java.awt.Point,
java.awt.Rectangle,
java.awt.Dimension);
...
with (SwingGui) {
var mybutton = new JButton(test);
var mypoint = new Point(10, 10);
var myframe = new JFrame();
...
}
</pre>
<p>
Previously such functionality was available only to embeddings that used <a href="apidocs/org/mozilla/javascript/ImporterTopLevel.html"><tt>org.mozilla.javascript.ImporterTopLevel</tt></a> class as the top level scope. The class provides additional <tt>importPackage()</tt> and <tt>importClass()</tt> global functions for scripts but their extensive usage has tendency to pollute the global name space with names of Java classes and prevents loaded classes from garbage collection.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=245882">Bugzilla 245882</a> for details.
</p>
<h4>Context customization API</h4>
<a href="apidocs/org/mozilla/javascript/ContextFactory.html"><tt>org.mozilla.javascript.ContextFactory</tt></a> provides new API for customization of <tt>org.mozilla.javascript.Context</tt> and ensures that application-specific Context subclasses will always be used when Rhino runtime needs to create Context instances.
</p>
<p>
See <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=255595">Bugzilla 245882</a> for details.
</p>
<h4>Support for Date.now()</h4>
<p>
<tt>Date.now()</tt> function which is a SpiderMonkey extension to ECMAScript standard is available now in Rhino. The function returns number of milliseconds passed since 1970-01-01 00:00:00 UTC.
</p>
<h4><a name="Rhino1.5R1-deprecation-removal"></a>Removal of deprecated classes</h4>
<p>
The following classes that were deprecated in Rhino 1.5R5 are no longer available in Rhino 1.6R1:
<ul>
<li><tt>org.mozilla.javascript.ClassNameHelper</tt></li>
<li><tt>org.mozilla.javascript.ClassRepository</tt></li>
</ul>
See documentation for <a href="apidocs/org/mozilla/javascript/optimizer/ClassCompiler.html"><tt>org.mozilla.javascript.optimizer.ClassCompiler</tt></a> that provides replacement for ClassNameHelper and ClassRepository.

JavaScript is a language that uses delegation rather than traditional class-based
inheritance. This is a large topic in itself, but for our purposes it gives
us an easy way to share a set of read-only variables across multiple scopes.

<h2>Sealed shared scopes</h2>
<p>The ECMAScript standard defines that scripts can add properties to all standard library objects and in many cases it is also possible to change or delete their properties as well. Such behavior may not be suitable with shared scopes since if a script by mistake adds a property to a library object from the shared scope, that object would not be garbage collected until there re active references to the shared scope potentially leading to memory leaks. In addition if a script alters some of the standard objects, the library may not work properly for other scripts. Such bugs are hard to debug and to remove a possibility for them to occur one can use seal the shared scope and all its objects.
<p>
A notion of a sealed object is a JavaScript extension supported by Rhino and it means that properties can not be added/deleted to the object and the existing object properties can not be changed. Any attempt to modify sealed object throws an exception. To seal all objects in the standard library pass <tt>true</tt> for the sealed argument when calling <tt>Context.initStandardObjects(ScriptableObject, boolean)</tt>:
<pre> ScriptableObject sealedSharedScope = cx.initStandardObjects(null, true);</pre>
This seals only all standard library objects, it does not seal the shared scope itself thus after calling <tt>initStandardObjects</tt>, <tt>sealedSharedScope</tt> cab be farther populated with application-specific objects and functions. Then after a custom initialization is done, one can seal the shared scope by calling <tt>ScriptableObject.sealObject()</tt>:
<pre> sealedSharedScope.sealObject();</pre>
Note that currently one needs to explicitly seal any additional properties he adds to the sealed shared scope since although after calling <tt>sealedSharedScope.sealObject();</tt> it would no be possible to set the additional properties to different values, one still would be able to alter the objects themselves.
<h2> Dynamic Scopes</h2>
There's one problem with the setup outlined above. Calls to functions in
JavaScript use <i>static scope</i>, which means that variables are first looked
up in the function and then, if not found there, in the lexically enclosing
scope. This causes problems if functions you define in your shared scope
need access to variables you define in your instance scope.
<p>With Rhino 1.5, it is possible to compile functions to use <i>dynamic
scope</i>. With dynamic scope, functions look at the top-level scope of the
calling function rather than their lexical scope. So we can store information
<p>With Rhino 1.6, it is possible to use <i>dynamic scope</i>. With dynamic scope, functions look at the top-level scope of the currently executed script
rather than their lexical scope. So we can store information
that varies across scopes in the instance scope yet still share functions
that manipulate that information reside in the shared scope. </p>

<p>You can execute a JavaScript file by putting the file name as an argument
to the shell class:
<pre>&nbsp;&nbsp;&nbsp; java org.mozilla.javascript.tools.shell.Main myScript.js</pre>
There are a number of options for evaluating scripts using the shell. See

LiveConnect: Communicating with Java from JavaScript</h2>
If you are planning to script Java using Rhino, you'll want to use LiveConnect,
which allows you to create Java classes and call Java methods from within
JavaScript. For example, here's a log from an interactive session. If you
type it in, you'll see a window with a button filling it.

<h2>
Accessing JavaBean Properties</h2>
Java classes can define JavaBean properties using getter and setter methods.
For example, the following class defines two properties:
<p><tt>public class Me {</tt>
<br><tt>&nbsp;&nbsp;&nbsp; public int getAge() { return age; }</tt>
<br><tt>&nbsp;&nbsp;&nbsp; public void setAge(int anAge) { age = anAge;
}</tt>
<br><tt>&nbsp;&nbsp;&nbsp; public String getSex() { return "male"; }</tt>
<br><tt>&nbsp;&nbsp;&nbsp; private int age;</tt>
<br><tt>};</tt>
<p>The two properties defined are <i>age</i> and <i>sex</i>. The <i>sex</i>
property is read-only: it has no setter.
<p>Using Rhino we can access the bean properties as if they where JavaScript
properties. We can also continue to call the methods that define the property.
<p><tt>js> me = new Packages.Me();</tt>
<br><tt>Me@93</tt>
<br><tt>js> me.getSex()</tt>
<br><tt>male</tt>
<br><tt>js> me.sex</tt>
<br><tt>male</tt>
<br><tt>js> me.age = 33;</tt>
<br><tt>33</tt>
<br><tt>js> me.age</tt>
<br><tt>33</tt>
<br><tt>js> me.getAge()</tt>
<br><tt>33</tt>
<br><tt>js></tt>
<p>Since the <i>sex</i> property is read-only, we are not allowed to write
to it.
<p><i>Note: JavaBean reflection is not available in versions of Rhino before
1.5.</i>
<br><tt></tt>&nbsp;
<h2>
Importing Java Classes and Packages</h2>
Above we saw the use of the <tt>importPackage</tt> function to import all
the classes from a particular Java package. There is also <tt>importClass</tt>,
which imports a single class:
<pre>$ java org.mozilla.javascript.tools.shell.Main
js> importClass(Packages.org.mozilla.javascript.Context)
js> cx = Context.enter()
<h2><a name="accessing" id="accessing">Accessing JavaBean Properties</a></h2>
<p>Java classes can define JavaBean properties using getter and setter methods.
For example, the following class defines two properties:</p>
<pre class="code">
public class Me {
public int getAge() { return age; }
public void setAge(int anAge) { age = anAge;
}
public String getSex() { return "male"; }
private int age;
};
</pre>
<p>The two properties defined are <var>age</var> and <var>sex</var>.
The <var>sex</var> property is read-only: it has no setter.</p>
<p>Using Rhino we can access the bean properties as if they where
JavaScript properties. We can also continue to call the methods that

Extending Java Classes and Implementing Java Interfaces with JavaScript</h2>
Starting from the example above of creating a Java frame using JavaScript,
we can add a listener for the button. Once we call <tt>addActionListener</tt>

Rhino actually creates a new Java class that implements <tt>ActionListener</tt>

<h2>
JavaAdapter constructor</h2>
Another way to create a JavaAdapter is to call the JavaAdapter constructor
explicitly. Using the JavaAdapter constructor gives you additional features
that cannot be had by "constructing" a Java interface as was done above.
<p>Instead of writing
<pre>&nbsp;&nbsp;&nbsp; buttonListener = java.awt.event.ActionListener(o)</pre>
above we can also write
<pre>&nbsp;&nbsp;&nbsp; buttonListener = new JavaAdapter(java.awt.event.ActionListener, o)</pre>

also implementing <tt>java.lang.Runnable</tt>, we would write

<p>&nbsp;&nbsp;&nbsp; <tt>new JavaAdapter(</tt><i>java-class</i>, [<i>java-class</i>,
...] <i>javascript-object</i><tt>)</tt>
<p>where at most one <i>java-class</i> is a Java class and the remaining

Java class, implements the Java interfaces, and forwards any calls to the

Example</h2>
<h4>Invocation</h4>
Here the shell is invoked three times from the command line. (The system
command prompt is shown as <tt>$</tt>.) The first invocation executes a
script specified on the command line itself. The next invocation has no
arguments, so the shell goes into interactive mode, reading and evaluating
each line as it is typed in. Finally, the last invocation executes a script
from a file and accesses arguments to the script itself.

Users can model and parameterize navigations and extractions, then wrap them in business processes for execution from a client application.

<p><a href="http://www.magoosoft.com">Magoo Software</a>
<br>"We've just released version 1.5 of MagooClient, an XML messaging client, with Rhino inside. The availability of Rhino 1.6R1 with E4X marks a significant breakthrough in the way that people work with XML content. Instead of merely editing, users can add their own custom logic to perform calculations, implement validation rules that test relationships between elements and crucially, add callouts to external Web Services to populate XML documents. There have been several attempts at this type of rich XML client in the past but none offer the familiarity, simplicity and adherence to standards offered by Rhino/JavaScript/E4X." -- John McGuire, CTO Magoo Software.
<p><a href="http://homepage.mac.com/pcbeard/JShell/">JShell</a>
<br>Rhino is used as the scripting language for the open source command
shell JShell written by Patrick Beard.
<p><a href="http://www.softcom.com">Softcom</a>
<br>The tight integration of Netscape's Java-based JavaScript 1.5 with
Softcom's Java-based RealPlayer plugin, RJ, enables Softcom to quickly
produce dynamic interactive video applications for our media/entertainment,
retail and professional education clients, helping us to synchronize the
full interactivity of the Web and e-commerce with streaming video, said
Chris O'Brien, president and COO of Softcom. For the enhanced Oscarcast
recently produced for E! Online during the Academy Awards, Softcom used
RJ to embed Netscape's JavaScript 1.5 in the RealPlayer, successfully integrating
interactive chat and Java games, along with streaming video, within the
RealPlayer.
<p><a href="http://www.tdiinc.com/">Technology Deployment International</a>
<br>"Technology Deployment International selected the Java-based Netscape
JavaScript engine to incorporate into the workflow module of our eBusiness
Management System (eBMS) allowing our customers to integrate business logic
into any workstep of their application," said Dr. Kelvin Liu, VP eBMS Development,
Technology Deployment International. "It has been easy to embed, the support
we received from the engineering team has been outstanding, and the performance
of the JavaScript code is almost identical to the equivalent Java."
<p><a href="http://www.runitsoft.com/">RUnit Software</a>
<br>RUnit Software uses Rhino as part of
solutions for business-process automation, for example
when the automation involves communicating with a
web-interface.
<p><a href="http://www.seppia.org/">Seppia</a>
<br>"Seppia is a simple technology to build and deploy any Java application.
It gains from the synergy of Java and JavaScript and a minimum set of clear
rules to organize their interaction. Seppia allows developers to create
stand-alone applications from constituent parts.
Each part is a module: a unit of function integrating seamlessly JavaScript
files, jar files and other resources.
Seppia uses Mozilla Rhino to empower its JavaScript engine.
Seppia will challenge the way you think of Java-based component computing."
<p><a href="http://www.xmoon.org">XMoon</a>
<br>XMoon is a dynamic OO (Object Oriented) opensource extension released under LGPL License for Jakarta Struts, powerful and easy to use.
XMoon lets you develop business logic classes following a fully Java compatible scripting language allowing execution of Java code at runtime without any access to a compiler.

enum.js
Implementing the interface java.util.Enumeration using the new syntax.
Note that this syntax is experimental only, and hasn't been approved
by ECMA.
The same functionality can be had without the new syntax using the
uglier syntax:
Implementing the interface java.util.Enumeration passing the object
with JavaScript implementation directly to the constructor.
This is a shorthand for JavaAdapter constructor:
var elements = new JavaAdapter(java.util.Enumeration, {
index: 0, elements: array,
hasMoreElements: function ...
nextElement: function ...
elements = new JavaAdapter(java.util.Enumeration, {
index: 0,
elements: array,
hasMoreElements: function ...
nextElement: function ...
});

/**
* Factory class that Rhino runtime use to create new {@link Context}
* instances or to notify about Context execution.
* <p>
* When Rhino runtime needs to create new {@link Context} instance during
* execution of {@link Context#enter()} or {@link Context}, it will call
* {@link #makeContext()} of the current global ContextFactory.
* See {@link #getGlobal()} and {@link #initGlobal(ContextFactory)}.
* <p>
* It is also possible to use explicit ContextFactory instances for Context
* creation. This is useful to have a set of independent Rhino runtime
* instances under single JVM. See {@link #call(ContextAction)}.
* <p>
* The following example demonstrates Context customization to terminate
* scripts running more then 10 seconds and to provide better compatibility
* with JavaScript code using MSIE-specific features.
* <pre>
