override

public Node override(Node parent,
            Node n)

Description copied from class: NodeVisitor

Given a tree rooted at n, the visitor has the option of overriding all traversal of the children of n. If no changes were made to n and the visitor wishes to prevent further traversal of the tree, then it should return n. If changes were made to the subtree, then the visitor should return a copy of n with appropriate changes. Finally, if the visitor does not wish to override traversal of the subtree rooted at n, then it should return null.

The default implementation of this method is to call override(n), as most subclasses do not need to know the parent of the node n.

Overrides:

override in class NodeVisitor

Parameters:

parent - The parent of n, null if n has no parent.

n - The root of the subtree to be traversed.

Returns:

A node if normal traversal is to stop, null if it is to continue.
