Construct an anonymous function. Parameters:   enclosingScope - the context the function was declared in Parameters:   superFxn - the function this function extends, or null Parameters:   fd - the shared function data, for all instances of this function Method Detail bopCast public Value bopCast(Value val) throws PackagedScriptObjectException(Code) Perform the cast operation, (a)b is equivalent to a.bopCast(b) Parameters:   val - the other value the result throws:   PackagedScriptObjectException - (NoSuchMemberException) callAsConstructor public Value callAsConstructor(StackFrame sf, MemberTable args) throws PackagedScriptObjectException(Code) Call this object as a constructor. Parameters:   sf - the current stack frame Parameters:   args - the arguments to the function, or null if none the newly constructed object throws:   PackagedScriptObjectException - See Also:   Function callAsExtends public Value callAsExtends(StackFrame sf, Scope scope, MemberTable args) throws PackagedScriptObjectException(Code) Call this object as a parent class constructor.

Parameters:   sf - the current stack frame Parameters:   args - the arguments to the function, or null if none the value returned by the function throws:   PackagedScriptObjectException - See Also:   Function castToString public String castToString() throws PackagedScriptObjectException(Code) Convert this object to a native java String value. a String value throws:   PackagedScriptObjectException - (NoSuchMethodException) extractJavadocComment public static Value extractJavadocComment(Vector specials, Value name, int[] argIds)(Code) extractJavadocComment public static Value extractJavadocComment(String str, Value name, Value[] argNames)(Code) extractJavadocCommentBody public static Value extractJavadocCommentBody(String str, Value name, Value[] argNames)(Code) getArgNames public Value[] getArgNames()(Code) Get the names of the arguments to the function, in order. If this function takes a variable number of arguments, the last name in the array is the "var-arg" variable, to which the array of all remaining arguments are bound. getComment public Value getComment()(Code) Get the comment block. If there was a javadoc comment block preceding the definition of this function in the src file, it can be accessed with this method. the function's comment, or null getMember public Value getMember(int id, boolean exception) throws PackagedScriptObjectException(Code) Get a member of this object. Parameters:   id - the id of the symbol that maps to the member Parameters:   exception - whether an exception should be thrown if themember object is not resolved a reference to the member throws:   PackagedScriptObjectException - (NoSuchMethodException) throws:   PackagedScriptObjectException - (NoSuchMemberException) getMinimumArgCount public int getMinimumArgCount()(Code) Get the minimum number of args that should be passed to this function. If Function.isVarArgs returns true, then it is possible to pass more arguments to this function, otherwise, you should pass exactly this number of args to the function. minimum number of args to pass when calling this function See Also:   Function.isVarArgs See Also:   Function.getArgNames getName public Value getName()(Code) Get the name of this function. An anonymous function will have the name "anon". the function's name getOverriden Value getOverriden()(Code) If this function overrides a value, this method returns it. Otherwise it returns null. getStaticMember final Value getStaticMember(int id)(Code) Get a static member of this function object. getSuper Value getSuper()(Code) Get the function that this function extends, or null if none. getTypeImpl protected Value getTypeImpl()(Code) Get the type of this object. The returned type doesn't have to take into account the possibility of a script type extending a built-in type, since that is handled by Function.getType . the object's type getTypeMember protected Value getTypeMember(Value obj, int id)(Code) Get a member of this type. This is used to interface to the java method of having members be attributes of a type. Regular object- script object's members are attributes of the object, but in the case of java types (including built-in types), the members are attributes of the type. Parameters:   obj - an object of this type Parameters:   id - the id of the symbol that maps to the member a reference to the member, or null isA public boolean isA(Value type)(Code) If this object is a type, determine if an instance of this type is an instance of the specified type, ie. if this is type, or a subclass. Parameters:   type - the type to compare this type to true or false throws:   PackagedScriptObjectException - (NoSuchMemberException) populateMemberSet protected void populateMemberSet(Set s, boolean debugger)(Code) Derived classes that implement Function.getMember should also implement this. Parameters:   s - the set to populate Parameters:   debugger - true if being used by debugger, inwhich case both public and private/protected field names should be returned See Also:   Function.getMember populateTypeMemberSet protected void populateTypeMemberSet(Set s, boolean debugger)(Code) Derived classes that implement Function.getTypeMember should also implement this. Parameters:   s - the set to populate Parameters:   debugger - true if being used by debugger, inwhich case both public and private/protected field names should be returned See Also:   Function.getTypeMember takesVarArgs public boolean takesVarArgs()(Code) Can this function be called with a variable number of arguments?
