Class GraphView

java.lang.Object
org.apache.jena.graph.impl.GraphBase
org.apache.jena.sparql.core.GraphView
All Implemented Interfaces:
org.apache.jena.atlas.lib.Sync, org.apache.jena.graph.Graph, org.apache.jena.graph.impl.GraphWithPerform, NamedGraph
public class GraphView extends org.apache.jena.graph.impl.GraphBase implements NamedGraph, org.apache.jena.atlas.lib.Sync
Implement a Graph as a view of the DatasetGraph. It maps graph operations to quad operations. GraphUnionRead provides a union graph that does not assume quads, but loops on graphs.
