org.dom4j.io Class SAXEventRecorder

java.lang.Object
  org.xml.sax.helpers.DefaultHandler
      org.dom4j.io.SAXEventRecorder

All Implemented Interfaces:: ContentHandler, DeclHandler, DTDHandler, EntityResolver, ErrorHandler, Externalizable, LexicalHandler, Serializable

public class SAXEventRecorder
extends DefaultHandler
implements LexicalHandler, DeclHandler, DTDHandler, Externalizable

Records SAX events such that they may be "replayed" at a later time. Provides an alternative serialization approach when externalizing a DOM4J document. Rather than serializing a document as text and re-parsing, the sax events may be serialized instead.

Example usage:

 
  
  
         SAXEventRecorder recorder = new SAXEventRecorder();
         SAXWriter saxWriter = new SAXWriter(recorder, recorder);
         saxWriter.write(document);
         out.writeObject(recorder);
         ...
         SAXEventRecorder recorder = (SAXEventRecorder)in.readObject();
         SAXContentHandler saxContentHandler = new SAXContentHandler();
         recorder.replay(saxContentHandler);
         Document document = saxContentHandler.getDocument();
