Example 6 with ParsedQuery

use of org.eclipse.rdf4j.query.parser.ParsedQuery in project rdf4j by eclipse.

the class SPARQLParserTest method testSES1922PathSequenceWithValueConstant.

@Test
public void testSES1922PathSequenceWithValueConstant() throws Exception {
    StringBuilder qb = new StringBuilder();
    qb.append("ASK {?A (<foo:bar>)/<foo:foo> <foo:objValue>} ");
    ParsedQuery q = parser.parseQuery(qb.toString(), null);
    TupleExpr te = q.getTupleExpr();
    assertNotNull(te);
    assertTrue(te instanceof Slice);
