Examples with Not org.openrdf.query.algebra.Not used on opensource projects

Example 1 with Not

use of org.openrdf.query.algebra.Not in project incubator-rya by apache.

the class AggregationPipelineQueryNodeTest method testExtend.

@Test
public void testExtend() {
    final AggregationPipelineQueryNode base = new AggregationPipelineQueryNode(collection, new LinkedList<>(), Sets.newHashSet("x", "y"), Sets.newHashSet("x", "y", "opt"), HashBiMap.create());
    // Extend with a mix of variables and constants
    List<ExtensionElem> extensionElements = Arrays.asList(new ExtensionElem(new Var("x"), "subject"), new ExtensionElem(new ValueConstant(RDF.TYPE), "predicate"), new ExtensionElem(new Var("y"), "object"));
    AggregationPipelineQueryNode node = base.clone();
    boolean success = node.extend(extensionElements);
    Assert.assertTrue(success);
    Assert.assertEquals(1, node.getPipeline().size());
    Assert.assertEquals(Sets.newHashSet("x", "y", "subject", "predicate", "object"), node.getAssuredBindingNames());
    Assert.assertEquals(Sets.newHashSet("x", "y", "subject", "predicate", "object", "opt"), node.getBindingNames());
    // Attempt to extend with an unsupported expression
    extensionElements = Arrays.asList(new ExtensionElem(new Var("x"), "subject"), new ExtensionElem(new Not(new ValueConstant(VF.createLiteral(true))), "notTrue"));
    node = base.clone();
    success = node.extend(extensionElements);
    Assert.assertFalse(success);
    Assert.assertEquals(base, node);
}

Example 2 with Not

use of org.openrdf.query.algebra.Not in project incubator-rya by apache.
