/**
|
||||
* The following class save decompilation information about the source.
|
||||
* Source information is returned from the parser as a String
|
||||
* associated with function nodes and with the toplevel script. When
|
||||
* saved in the constant pool of a class, this string will be UTF-8
|
||||
* encoded, and token values will occupy a single byte.
|
||||
|
||||
* Source is saved (mostly) as token numbers. The tokens saved pretty
|
||||
* much correspond to the token stream of a 'canonical' representation
|
||||
* of the input program, as directed by the parser. (There were a few
|
||||
* cases where tokens could have been left out where decompiler could
|
||||
* easily reconstruct them, but I left them in for clarity). (I also
|
||||
* looked adding source collection to TokenStream instead, where I
|
||||
* could have limited the changes to a few lines in getToken... but
|
||||
* this wouldn't have saved any space in the resulting source
|
||||
* representation, and would have meant that I'd have to duplicate
|
||||
* parser logic in the decompiler to disambiguate situations where
|
||||
* newlines are important.) The function decompile expands the
|
||||
* tokens back into their string representations, using simple
|
||||
* lookahead to correct spacing and indentation.
|
||||
*
|
||||
* Assignments are saved as two-token pairs (Token.ASSIGN, op). Number tokens
|
||||
* are stored inline, as a NUMBER token, a character representing the type, and
|
||||
* either 1 or 4 characters representing the bit-encoding of the number. String
|
||||
* types NAME, STRING and OBJECT are currently stored as a token type,
|
||||
* followed by a character giving the length of the string (assumed to
|
||||
* be less than 2^16), followed by the characters of the string
|
||||
* inlined into the source string. Changing this to some reference to
|
||||
* to the string in the compiled class' constant pool would probably
|
||||
* save a lot of space... but would require some method of deriving
|
||||
* the final constant pool entry from information available at parse
|
||||
* time.

|
||||
* upon the type of the parameter. A parameter type of
|
||||
* Object specifies that no conversions are to be done. A parameter
|
||||
* of type String will use Context.toString to convert arguments.
|
||||
* Similarly, parameters of type double, boolean, and Scriptable
|
||||
* will cause Context.toNumber, Context.toBoolean, and
|
||||
* Context.toObject, respectively, to be called.<p>
|
||||
*
|
||||
* If the method is not static, the Java 'this' value will
|
||||
* correspond to the JavaScript 'this' value. Any attempt
|
||||
* 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 = new ImporterTopLevel(cx);
|
||||
* </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()
|
||||
* []
