- /* dtoa for IEEE arithmetic (dmg): convert double to ASCII string.
- *
- * Inspired by "How to Print Floating-Point Numbers Accurately" by
- * Guy L. Steele, Jr. and Jon L. White [Proc. ACM SIGPLAN '90, pp. 92-101].
- *
- * Modifications:
- * 1. Rather than iterating, we use a simple numeric overestimate
- * to determine k = floor(log10(d)). We scale relevant
- * quantities using O(log2(k)) rather than O(k) multiplications.
- * 2. For some modes > 2 (corresponding to ecvt and fcvt), we don't
- * try to generate digits strictly left to right. Instead, we
- * compute with fewer bits and propagate the carry if necessary
- * when rounding the final digit up. This is often faster.
- * 3. Under the assumption that input will be rounded nearest,
- * mode 0 renders 1e23 as 1e23 rather than 9.999999999999999e22.
- * That is, we allow equality in stopping tests when the
- * round-nearest rule will give the same floating-point value
- * as would satisfaction of the stopping test with strict
- * inequality.
- * 4. We remove common factors of powers of 2 from relevant
- * quantities.
- * 5. When converting floating-point integers less than 1e16,
- * we use floating-point arithmetic rather than resorting
- * to multiple-precision integers.
- * 6. When asked to produce fewer than 15 digits, we first try
- * to get by with floating-point arithmetic; we resort to
- * multiple-precision integer arithmetic only if we cannot
- * guarantee that the floating-point calculation has given
- * the correctly rounded result. For k requested digits and
- * "uniformly" distributed input, the probability is
- * something like 10^(k-15) that we must resort to the Long
- * calculation.

-/**
- * 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.

- * Create a JavaScript function object from a Java method.
- *
- * <p>The <code>member</code> argument must be either a java.lang.reflect.Method
- * or a java.lang.reflect.Constructor and must match one of two forms.<p>
- *
- * The first form is a member with zero or more parameters
- * of the following types: Object, String, boolean, Scriptable,
- * int, or double. The Long type is not supported
- * because the double representation of a long (which is the
- * EMCA-mandated storage type for Numbers) may lose precision.
- * If the member is a Method, the return value must be void or one
- * of the types allowed for parameters.<p>
- *
- * The runtime will perform appropriate conversions based
- * 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()
- * []

- * Does consistent-return analysis on the function body when strict mode is

- *
- * function (x) { return (x+1) }
- * is ok, but
- * function (x) { if (x < 0) return (x+1); }
- * is not becuase the function can potentially return a value when the
- * condition is satisfied and if not, the function does not explicitly
- * return value.
- *
- * This extends to checking mismatches such as "return" and "return <value>"
- * used in the same function. Warnings are not emitted if inconsistent
- * returns exist in code that can be statically shown to be unreachable.
- * Ex.
- * function (x) { while (true) { ... if (..) { return value } ... } }
- * emits no warning. However if the loop had a break statement, then a
- * warning would be emitted.

- * The consistency analysis looks at control structures such as loops, ifs,

- * Caveat: Since the parser flattens many control structures into almost

- * analyser is written to taken advantage of patterns of code generated by
- * the parser (for loops, try blocks and such) and does not do a full

- * Defines JavaScript objects from a Java class that implements Scriptable.
- *
- * If the given class has a method
- * <pre>
- * static void init(Context cx, Scriptable scope, boolean sealed);</pre>
- *
- * or its compatibility form
- * <pre>
- * static void init(Scriptable scope);</pre>
- *
- * then it is invoked and no further initialization is done.<p>
- *
- * However, if no such a method is found, then the class's constructors and
- * methods are used to initialize a class in the following manner.<p>
- *
- * First, the zero-parameter constructor of the class is called to
- * create the prototype. If no such constructor exists,
- * a {@link EvaluatorException} is thrown. <p>
- *
- * Next, all methods are scanned for special prefixes that indicate that they
- * have special meaning for defining JavaScript objects.
- * These special prefixes are
- * <ul>
- * <li><code>jsFunction_</code> for a JavaScript function
- * <li><code>jsStaticFunction_</code> for a JavaScript function that
- * is a property of the constructor
- * <li><code>jsGet_</code> for a getter of a JavaScript property
- * <li><code>jsSet_</code> for a setter of a JavaScript property
- * <li><code>jsConstructor</code> for a JavaScript function that
- * is the constructor
- * </ul><p>
- *
- * If the method's name begins with "jsFunction_", a JavaScript function
- * is created with a name formed from the rest of the Java method name
- * following "jsFunction_". So a Java method named "jsFunction_foo" will
- * define a JavaScript method "foo". Calling this JavaScript function
- * will cause the Java method to be called. The parameters of the method
- * must be of number and types as defined by the FunctionObject class.
- * The JavaScript function is then added as a property
- * of the prototype. <p>
- *
- * If the method's name begins with "jsStaticFunction_", it is handled
- * similarly except that the resulting JavaScript function is added as a
- * property of the constructor object. The Java method must be static.
- *
- * If the method's name begins with "jsGet_" or "jsSet_", the method is
- * considered to define a property. Accesses to the defined property
- * will result in calls to these getter and setter methods. If no
- * setter is defined, the property is defined as READONLY.<p>
- *
- * If the method's name is "jsConstructor", the method is
- * considered to define the body of the constructor. Only one
- * method of this name may be defined.
- * If no method is found that can serve as constructor, a Java
- * constructor will be selected to serve as the JavaScript
- * constructor in the following manner. If the class has only one
- * Java constructor, that constructor is used to define
- * the JavaScript constructor. If the the class has two constructors,
- * one must be the zero-argument constructor (otherwise an
- * {@link EvaluatorException} would have already been thrown
- * when the prototype was to be created). In this case
- * the Java constructor with one or more parameters will be used
- * to define the JavaScript constructor. If the class has three
- * or more constructors, an {@link EvaluatorException}
- * will be thrown.<p>
- *
- * Finally, if there is a method
- * <pre>
- * static void finishInit(Scriptable scope, FunctionObject constructor,
- * Scriptable prototype)</pre>
- *
- * it will be called to finish any initialization. The <code>scope</code>
- * argument will be passed, along with the newly created constructor and
- * the newly created prototype.<p>
