Class TreeNodeList

java.lang.Object
  TreeNode
      TreeNodeList

public class TreeNodeList

extends TreeNode

TreeNodeList extends TreeNode by adding a node component and a siblings component. The node is a reference to a single TreeNode. The siblings component is a reference to a TreeNodeList, which may contain zero or more additional TreeNodes. Hence, TreeNodeList is used to represent list constructs in a parse tree. It can equivalently be viewed as a way to represent n-ary constructs.

Field Summary

TreeNode	node Reference to the first node of this (sub)list.
TreeNodeList	siblings Reference to the rest of this (sub)list
