Class PelletGraphListener

java.lang.Object

org.mindswap.pellet.jena.PelletGraphListener

All Implemented Interfaces:

org.apache.jena.graph.GraphListener

public class PelletGraphListener
extends Object
implements org.apache.jena.graph.GraphListener

A graph listener that listens to graph change events and if possible processes the change event. The listener is passed a possibly union graph but the listener is attached only to leaf (non-union) graphs. The listener keeps track which graph is changed and also checks if subgraphs are added or removed from the root graph.
