public class XMLFilterImpl extends Object implements XMLFilter, EntityResolver, DTDHandler, ContentHandler, ErrorHandler
This module, both source code and documentation, is in the Public Domain, and comes with NO WARRANTY.
This class is designed to sit between an
XMLReader
and the client application's event handlers. By default, it
does nothing but pass requests up to the reader and events
on to the handlers unmodified, but subclasses can override
specific methods to modify the event stream or the configuration
requests as they pass through.
Since: SAX 2.0
Version: 2.0r2pre
