Examples of TupleQuery

org.openrdf.query.TupleQuery
org.sindice.siren.search.node.TupleQuery
A {@link NodeQuery} that matches tuples, i.e., a boolean combination of{@link NodeQuery} having the same parent node.

Examples of org.openrdf.query.TupleQuery

    testCon.add(alice, name, nameAlice);
    testCon.add(alice, mbox, mboxAlice);
    testCon.add(bob, name, nameBob);
    testCon.add(bob, mbox, mboxBob);


    TupleQuery query = testCon.prepareTupleQuery(QueryLanguage.SERQL, "SELECT o FROM {} P {o}");
    int total = query.evaluate().asList().size();
    query.setOffset(1);
    assertEquals(total - 1, query.evaluate().asList().size());
