WebLogic Server 6.0sp2 API Reference

weblogic.apache.xalan.xpath.xml
Class TreeWalker

java.lang.Object

  +--weblogic.apache.xalan.xpath.xml.TreeWalker

public class TreeWalker

extends java.lang.Object

This class does a pre-order walk of the DOM tree, calling the FormatterListener interface as it goes.

This class is based on an implementation from the Apache XML Project. In future releases the XML parser, XSLT processor, and associated classes will likely be updated to be based on a later version of the Apache implementations. Since Apache does not guarantee backwards compatibility between versions of their software, we cannot guarantee backwards compatibility of any of the classes contained in the weblogic.apache package or sub-packages.
