All Implemented Interfaces:

ISourcePositionHolder, ParseResult

Direct Known Subclasses:

ArrayNode, BlockNode, DNode

public class ListNode
extends 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.
