XmlnsContentHandler

public class ProxyContentHandler
extends org.xml.sax.helpers.DefaultHandler

A proxy content handler that passes all SAX events as-is to the proxied handler.

As a convenience this class inherits the DefaultHandler class instead of just the ContentHandler interface. This makes it possible to use this class as an adapter when using methods like SAXParser.parse(String, DefaultHandler) that expect a DefaultHandler instance instead of a ContentHandler.
