Class DelegatingContentHandler

java.lang.Object
  extended byorg.apache.fop.util.DelegatingContentHandler
All Implemented Interfaces:
org.xml.sax.ContentHandler, org.xml.sax.DTDHandler, org.xml.sax.EntityResolver, org.xml.sax.ErrorHandler, org.xml.sax.ext.LexicalHandler

public class DelegatingContentHandler
extends java.lang.Object
implements org.xml.sax.EntityResolver, org.xml.sax.DTDHandler, org.xml.sax.ContentHandler, org.xml.sax.ext.LexicalHandler, org.xml.sax.ErrorHandler

SAX 2 Event Handler which simply delegates all calls to another ContentHandler. Subclasses can do additional processing. This class is the passive counterpart to XMLFilterImpl.

The ContentHandler is the only instance that is required. All others (DTDHandler, EntityResolver, LexicalHandler and ErrorHandler) may be ignored.
