java.lang.Objectcom.hp.hpl.jena.sparql.core.DatasetGraphBase
public abstract class DatasetGraphBase
DatasetGraph framework : readonly dataset need only provide find(g,s,p,o), getGraph() and getDefaultGraph() although it may wish to override other operations and do better.
Other implementations include:
DatasetGraphBase that adds an implementation of find based on default / named graphs.DatasetGraphCollection that adds mutating quad operations mapped to a collection of graphs.DatasetGraphQuad that maps graph operations to a quad view.

contains(com.hp.hpl.jena.graph.Node g,
com.hp.hpl.jena.graph.Node s,
com.hp.hpl.jena.graph.Node p,
com.hp.hpl.jena.graph.Node o)
