public final class TreeWalker
extends java.lang.Object

This class does a pre-order walk of the DOM tree, calling a ContentHandler interface as it goes. This class is a copy of the one in org.apache.xml.utils. It exists to cut the serializers dependancy on that package.

Usage:
**For internal use only**

Constructor Detail

TreeWalker

public TreeWalker(ContentHandler ch)

TreeWalker

public TreeWalker(ContentHandler contentHandler,
                  java.lang.String systemId)
Constructor.
Parameters:
contentHandler - The implemention of the contentHandler operation (toXMLString, digest, ...)
Method Detail

getContentHandler

public ContentHandler getContentHandler()
Get the ContentHandler used for the tree walk.
Returns:
the ContentHandler used for the tree walk

traverse

public void traverse(Node pos)
              throws SAXException
Perform a pre-order traversal non-recursive style. Note that TreeWalker assumes that the subtree is intended to represent a complete (though not necessarily well-formed) document and, during a traversal, startDocument and endDocument will always be issued to the SAX listener.
Parameters:
pos - Node in the tree where to start traversal
Throws:
TransformerException -  

traverse

public void traverse(Node pos,
                     Node top)
              throws SAXException
Perform a pre-order traversal non-recursive style. Note that TreeWalker assumes that the subtree is intended to represent a complete (though not necessarily well-formed) document and, during a traversal, startDocument and endDocument will always be issued to the SAX listener.
Parameters:
pos - Node in the tree where to start traversal
top - Node in the tree where to end traversal
Throws:
TransformerException -
