public class TreeTranslator
extends JCTree.Visitor

A subclass of Tree.Visitor, this class defines a general tree translator pattern. Translation proceeds recursively in left-to-right order down a tree, constructing translated nodes by overwriting existing ones. There is one visitor method in this class for every possible kind of tree node. To obtain a specific translator, it suffices to override those visitor methods which do some interesting work. The translator class itself takes care of all navigational aspects.

This is NOT part of any API supported by Sun Microsystems. If you write code that depends on this, you do so at your own risk. This code and its internal interfaces are subject to change or deletion without notice.
