All Implemented Interfaces:

public class XGMMLDelegatorHandler
extends DefaultHandler

Delegator handler.

Handles the SAX parser events and invokes the XGMMLHandler methods uing refection API.

This handler handles the startDocument, endDocument, startElement and endElementEvents from SAX2 parser.
If an event was received this handler uses a second handler to process the events. There for the second handler must implement startXElement and endXElement where X is the tag name to be processed.

Example:
If you want to process <node> tags, your handler must implement a startNodeElement and a endNodeElement method. These method are automatically invoked using reflection API.
