Example 1 with GraphViewSwitchable

use of org.apache.jena.tdb2.store.GraphViewSwitchable in project jena by apache.

the class StageGeneratorDirectTDB method execute.

@Override
public QueryIterator execute(BasicPattern pattern, QueryIterator input, ExecutionContext execCxt) {
    // --- In case this isn't for TDB2
    Graph g = execCxt.getActiveGraph();

        GraphViewSwitchable gvs = (GraphViewSwitchable) g;
        g = gvs.getBaseGraph();
    }
    if (!(g instanceof GraphTDB))
        // Not us - bounce up the StageGenerator chain
        return above.execute(pattern, input, execCxt);
    GraphTDB graph = (GraphTDB) g;
    Predicate<Tuple<NodeId>> filter = QC2.getFilter(execCxt.getContext());
