Class ListNode

java.lang.Object

org.jruby.ast.Node

org.jruby.ast.ListNode

All Implemented Interfaces:

java.lang.Iterable<Node>, ISourcePosition, ISourcePositionHolder, PositionAware

Direct Known Subclasses:

ArrayNode, BlockNode, DNode, ZArrayNode

public class ListNode
extends Node
implements java.lang.Iterable<Node>

All Nodes which have a list representation inherit this. This is also used as generic container for additional information that is not directly evaluated. In particular, f_arg production rule uses this to capture arg information for the editor projects who want position info saved.
