C# Класс Rhino.Ast.FunctionNode

A JavaScript function declaration or expression.

Node type is Rhino.Token.FUNCTION .

FunctionDeclaration : function Identifier ( FormalParameterListopt ) { FunctionBody } FunctionExpression : function Identifieropt ( FormalParameterListopt ) { FunctionBody } FormalParameterList : Identifier FormalParameterList , Identifier FunctionBody : SourceElements Program : SourceElements SourceElements : SourceElement SourceElements SourceElement SourceElement : Statement FunctionDeclaration

JavaScript 1.8 introduces "function closures" of the form

function ([params] ) Expression

In this case the FunctionNode node will have no body but will have an expression.

Наследование: ScriptNode

Метод	Описание
AddFunction ( Rhino fnNode ) : int
AddLiveLocals ( Node node, int locals ) : void
AddParam ( AstNode param ) : void	Adds a parameter to the function parameter list. Adds a parameter to the function parameter list. Sets the parent of the param node to this node.

FunctionNode ( ) : System.Collections.Generic
FunctionNode ( int pos ) : System.Collections.Generic
FunctionNode ( int pos, Name name ) : System.Collections.Generic
GetBody ( ) : AstNode	Returns function body. Returns function body. Normally a Block , but can be a plain AstNode if it's a function closure.
GetFunctionName ( ) : Name	Returns function name
GetFunctionType ( ) : int	Returns the function type (statement, expr, statement expr)
GetLiveLocals ( ) : int[]>.IDictionary

IsSetter ( ) : bool
RequiresActivation ( ) : bool	Return true if this function requires an Ecma-262 Activation object. Return true if this function requires an Ecma-262 Activation object. The Activation object is implemented by Rhino.NativeCall , and is fairly expensive to create, so when possible, the interpreter attempts to use a plain call frame instead.

Also sets the encoded source bounds based on the body bounds. Assumes the function node absolute position has already been set, and the body node's absolute position and length are set.

SetMemberExprNode ( AstNode node ) : void	Rhino supports a nonstandard Ecma extension that allows you to say, for instance, function a.b.c(arg1, arg) {...}, and it will be rewritten at codegen time to: a.b.c = function(arg1, arg2) {...} If we detect an expression other than a simple Name in the position where a function name was expected, we record that expression here. Rhino supports a nonstandard Ecma extension that allows you to say, for instance, function a.b.c(arg1, arg) {...}, and it will be rewritten at codegen time to: a.b.c = function(arg1, arg2) {...} If we detect an expression other than a simple Name in the position where a function name was expected, we record that expression here.
