C# Class Rhino.Ast.ArrayLiteral

AST node for an Array literal.

AST node for an Array literal. The elements list will always be non- null , although the list will have no elements if the Array literal is empty.

Node type is Rhino.Token.ARRAYLIT .

ArrayLiteral : [ Elisionopt ] [ ElementList ] [ ElementList , Elisionopt ] ElementList : Elisionopt AssignmentExpression ElementList , Elisionopt AssignmentExpression Elision : , Elision ,

Inheritance: AstNode, DestructuringForm

Public Methods

Method	Description
AddElement ( AstNode element ) : void	Adds an element to the list, and sets its parent to this node. Adds an element to the list, and sets its parent to this node.
ArrayLiteral ( ) : System
ArrayLiteral ( int pos ) : System
ArrayLiteral ( int pos, int len ) : System
GetDestructuringLength ( ) : int	Returns destructuring length
GetElement ( int index ) : AstNode	Returns element at specified index. Returns element at specified index.
GetElements ( ) : IList	Returns the element list
GetSize ( ) : int	Returns the number of elements in this `Array` literal, including empty elements.
GetSkipCount ( ) : int	Used by code generator. Used by code generator.
IsDestructuring ( ) : bool	Returns true if this node is in a destructuring position: a function parameter, the target of a variable initializer, the iterator of a for..in loop, etc. Returns true if this node is in a destructuring position: a function parameter, the target of a variable initializer, the iterator of a for..in loop, etc.
SetDestructuringLength ( int destructuringLength ) : void	Sets destructuring length. Sets destructuring length. This is set by the parser and used by the code generator. `for ([a,] in obj)` is legal, but `for ([a] in obj)` is not since we have both key and value supplied. The difference is only meaningful in array literals used in destructuring-assignment contexts.
SetElements ( IList elements ) : void	Sets the element list, and sets each element's parent to this node. Sets the element list, and sets each element's parent to this node.
SetIsDestructuring ( bool destructuring ) : void	Marks this node as being a destructuring form - that is, appearing in a context such as `for ([a, b] in ...)` where it's the target of a destructuring assignment.
SetSkipCount ( int count ) : void	Used by code generator. Used by code generator.
ToSource ( int depth ) : string
Visit ( NodeVisitor v ) : void	Visits this node, then visits its element expressions in order. Visits this node, then visits its element expressions in order. Any empty elements are represented by EmptyExpression objects, so the callback will never be passed `null` .

Returns the number of elements in this Array literal, including empty elements.

public GetSize ( ) : int
return	int

GetSkipCount() public method

Used by code generator.

public GetSkipCount ( ) : int
return	int

IsDestructuring() public method

Returns true if this node is in a destructuring position: a function parameter, the target of a variable initializer, the iterator of a for..in loop, etc.

public IsDestructuring ( ) : bool
return	bool

SetDestructuringLength() public method

Sets destructuring length.

Sets destructuring length. This is set by the parser and used by the code generator. for ([a,] in obj) is legal, but for ([a] in obj) is not since we have both key and value supplied. The difference is only meaningful in array literals used in destructuring-assignment contexts.

public SetDestructuringLength ( int destructuringLength ) : void
destructuringLength	int
return	void

SetElements() public method

Sets the element list, and sets each element's parent to this node.

public SetElements ( IList elements ) : void
elements	IList	/// the element list. Can be /// `null` /// . ///
return	void

SetIsDestructuring() public method
