public class TreeScanner
extends JCTree.Visitor

A subclass of Tree.Visitor, this class defines a general tree scanner pattern. Translation proceeds recursively in left-to-right order down a tree. There is one visitor method in this class for every possible kind of tree node. To obtain a specific scanner, it suffices to override those visitor methods which do some interesting work. The scanner 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. TreeScanners do not descend into brackets.
