Example 21 with Element

use of org.apache.jena.sparql.syntax.Element in project jena by apache.

the class AbstractTestUpdateGraph method testModify2.

@Test

    // Use blank nodes (will expose any problems in serialization when spill occurs)
    Triple t = new Triple(org.apache.jena.graph.NodeFactory.createBlankNode(), p, o2);
    DatasetGraph gStore = getEmptyDatasetGraph();
    // Set the threshold to in order to force spill to disk
    gStore.getContext().set(ARQ.spillToDiskThreshold, 0L);
    defaultGraphData(gStore, data(t));
    namedGraphData(gStore, graphIRI, data(t));
    UpdateModify modify = new UpdateModify();
    Element element = QueryFactory.createElement("{ ?s <http://example/p> ?o }");
