Class DatasetGraphMonitor

java.lang.Object

com.hp.hpl.jena.sparql.core.DatasetGraphWrapper

com.hp.hpl.jena.sparql.core.DatasetGraphMonitor

All Implemented Interfaces:

DatasetGraph, Closeable

public class DatasetGraphMonitor
extends DatasetGraphWrapper

Connect a DatasetChanges instance to a DatasetGraph. Any add or delete to the DatasetGraph is notified to the monitoring object with a QuadAction to indicate the change made.
