|

* Matrix: An example host object class that implements the Scriptable interface.
|
||||
*
|
||||
* Built-in JavaScript arrays don't handle multiple dimensions gracefully: the
|
||||
* script writer must create every array in an array of arrays. The Matrix class
|
||||
* takes care of that by automatically allocating arrays for every index that
|
||||
* is accessed. What's more, the Matrix constructor takes a integer argument
|
||||
* that specifies the dimension of the Matrix. If m is a Matrix with dimension 3,
|
||||
* then m[0] will be a Matrix with dimension 1, and m[0][0] will be an Array.
|
||||
*
|
||||
* Here's a shell session showing the Matrix object in action:
|
||||
* <pre>
|
||||
* js> defineClass("Matrix")
|
||||
* js> m = new Matrix(2); <i>A constructor call, see <a href="#Matrix">Matrix</a> below.</i>
|
||||
* [object Matrix] <i>The "Matrix" here comes from <a href"#getClassName">getClassName</a>.</i>
|
||||
* js> version(120); <i>switch to JavaScript1.2 to see arrays better</i>
|
||||
* 0
|
||||
* js> m[0][0] = 3;
|
||||
* 3
|
||||
* js> m[0]; <i>an array was created automatically!</i>
|
||||
* [3]
|
||||
* js> m[1]; <i>array is created even if we don't set a value</i>
|
||||
* []
|
||||
* js> m.dim; <i>we can access the "dim" property</i>
|
||||

|
||||
* to call the function with a 'this' value that is not
|
||||
* of the right Java type will result in an error.<p>
|
||||
*
|
||||
* The second form is the variable arguments (or "varargs")
|
||||
* form. If the FunctionObject will be used as a constructor,
|
||||
* the member must have the following parameters
|
||||
* <pre>
|
||||
* (Context cx, Object[] args, Function ctorObj,
|
||||
* boolean inNewExpr)</pre>
|
||||
* and if it is a Method, be static and return an Object result.<p>
|
||||
*
|
||||
* Otherwise, if the FunctionObject will <i>not</i> be used to define a
|
||||
* constructor, the member must be a static Method with parameters
|
||||
* (Context cx, Scriptable thisObj, Object[] args,
|
||||
* Function funObj) </pre>
|
||||
* <pre>
|
||||
* and an Object result.<p>
|
||||
*
|
||||
* When the function varargs form is called as part of a function call,
|
||||
* the <code>args</code> parameter contains the
|
||||
* arguments, with <code>thisObj</code>
|
||||
* set to the JavaScript 'this' value. <code>funObj</code>
|
||||
* is the function object for the invoked function.<p>
|
||||
*
|
||||
* When the constructor varargs form is called or invoked while evaluating
|
||||
* a <code>new</code> expression, <code>args</code> contains the
|
||||
* arguments, <code>ctorObj</code> refers to this FunctionObject, and
|
||||
* <code>inNewExpr</code> is true if and only if a <code>new</code>
|
||||
* expression caused the call. This supports defining a function that
|
||||
* has different behavior when called as a constructor than when
|
||||
* invoked as a normal function call. (For example, the Boolean
|
||||
* constructor, when called as a function,

* will convert to boolean rather than creating a new object.)<p>

/**
|
||||
* Class ImporterTopLevel
|
||||
*
|
||||
* This class defines a ScriptableObject that can be instantiated
|
||||
* as a top-level ("global") object to provide functionality similar
|
||||
* to Java's "import" statement.
|
||||
* <p>
|
||||
* This class can be used to create a top-level scope using the following code:
|
||||
* <pre>
|
||||
* Scriptable scope = cx.initStandardObjects(new ImporterTopLevel());
|
||||
* </pre>
|
||||
* Then JavaScript code will have access to the following methods:
|
||||
* <ul>
|
||||
* <li>importClass - will "import" a class by making its unqualified name
|
||||
* available as a property of the top-level scope
|
||||
* <li>importPackage - will "import" all the classes of the package by
|
||||
* searching for unqualified names as classes qualified
|
||||
* by the given package.
|
||||
* </ul>
|
||||
* The following code from the shell illustrates this use:
|
||||
* <pre>
|
||||
* js> importClass(java.io.File)
|
||||
* js> f = new File('help.txt')
|
||||
* help.txt
|
||||
* js> importPackage(java.util)
|
||||
* js> v = new Vector()
|
||||
* []
