Example 41 with Literal

use of org.apache.jena.rdf.model.Literal in project jena by apache.

the class TestDatasetWithLuceneStoredLiterals method testLiteralValue.

@Test
public void testLiteralValue() {
    // test basic capturing of the literal value in a variable
    final String turtle = PF_DATA;
    String queryString = StrUtils.strjoinNL(QUERY_PROLOG, "SELECT ?s ?literal", "WHERE {", "    (?s ?score ?literal) text:query ('text') .", "}");
    Set<String> expectedURIs = new HashSet<>();
    expectedURIs.addAll(Arrays.asList(R_S1));
    Map<String, Literal> literals = doTestSearchWithLiterals(turtle, queryString, expectedURIs);
    Literal value = literals.get(R_S1);
    assertNotNull(value);
    assertEquals(NodeFactory.createLiteral("text"), value.asNode());
}
