java.lang.Object org.ajax4jsf.xml.serializer.TreeWalker
public final class TreeWalker
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.
