Class SafeGraph

java.lang.Object

org.apache.jena.graph.impl.WrappedGraph

org.apache.jena.reasoner.rulesys.impl.SafeGraph

All Implemented Interfaces:

Graph, GraphWithPerform

public class SafeGraph
extends WrappedGraph
implements Graph

A SafeGraph wraps a graph which might contain generalized RDF triples and hides them from API queries so that consumers of it are safe (but can use getRawGraph() to get back the unsafe graph.
