      TreeNode4

Direct Known Subclasses:

TypeNode

public class TreeNode4

extends TreeNode

TreeNode4 extends TreeNode by adding four child components, which are references other TreeNodes. Hence, TreeNode4 is used to represent quartinary syntactic constructs in a parse tree.

Field Summary

TreeNode	child1 Reference to the left child of this node.
TreeNode	child2 Reference to the first middle (or second, or third-from-the-last) child of this node.
TreeNode	child3 Reference to the second middle (or third, or next-to-the-last) child of this node.
TreeNode	child4 Reference to the right (or fourth, or last, or rightmost, or whatever-the-heck-you-want-to-call-it) child of this node.

Constructor Summary

TreeNode4(int id, TreeNode child1, TreeNode child2, TreeNode child3, TreeNode child4)
Construct this with the given id and child TreeNode references.

TreeNode4(int id, TreeNode child1, TreeNode child2, TreeNode child3, TreeNode child4, int line, int column)
A la the other constructor, but with line and column numbers.

Method Summary

java.lang.String

toString(int level) Return the String representation of this subtree, which is the String value of its ID, followed on the next four indented lines by the recursive toString of its four children.
