Examples of com.hp.hpl.jena.graph.compose.Union

com.hp.hpl.jena.graph.compose.Union
A class representing the dynamic union of two graphs. Addition only affects the left operand, deletion affects both. @see MultiUnion

        tdata.add(new Triple(p, RDFS.subPropertyOf.asNode(), q));
        tdata.add(new Triple(q, RDFS.subPropertyOf.asNode(), r));
        tdata.add(new Triple(r, RDFS.domain.asNode(), D));
        Graph data = Factory.createGraphMem();
        data.add(new Triple(a, p, b));
        InfGraph igraph = ReasonerRegistry.getRDFSReasoner().bind(new Union(tdata, data));
        TestUtil.assertIteratorValues(this, igraph.find(a, ty, null),
        new Object[] {
            new Triple(a, ty, D),
            new Triple(a, ty, RDFS.Resource.asNode()),
        });
