Class SAXFilterDefaultHandler

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      echoxul.util.sax.SAXFilterDefaultHandler

All Implemented Interfaces:

org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler, org.xml.sax.ext.LexicalHandler

Direct Known Subclasses:

DebugSAXFilterDefaultHandler, SAXTrimmingFilter

public class SAXFilterDefaultHandler

extends org.xml.sax.helpers.DefaultHandler

implements org.xml.sax.ext.LexicalHandler

Utility base class for defining a DefaultHandler which delegates all of its calls out to a parent DefaultHandler. Subclasses can override any of the methods to alter what the parent DefaultHandler sees. This class can be easily used for "cosmetic" changes to the XML which would be difficult to make at a higher level.
