Class GraphToXGMMLSAXHandler

java.lang.Object

salvo.jesus.graph.xml.GraphToXGMMLSAXHandler

All Implemented Interfaces:

GraphToXMLHandler

public class GraphToXGMMLSAXHandler
extends Object
implements GraphToXMLHandler

An implmentation of GraphToXMLHandler that serializes a Graph and/or VisualGraph to XGMML via SAX.

This class simply delegates handling of events to either the inner class GraphToXGMMLSAXHandler.GraphHandler or GraphToXGMMLSAXHandler.VisualGraphHandler, depending on which method between startSerialize() is called. Users should simply create an instance of this class and should not be concerned of the inner classes, and call the appropriate overloaded startSerialize() method.
