use of org.apache.jena.query.ResultSet in project jena by apache.

the class TestResultSet method test_RS_peeking_5.

@Test
public void test_RS_peeking_5() {

    // Move on the inner result set independently
    inner.next();
    // Since we fiddled with the underlying result set there won't be further elements available anymore
    assertFalse(rs.hasNext());
}

Example 54 with ResultSet

use of org.apache.jena.query.ResultSet in project jena by apache.

Example 55 with ResultSet

use of org.apache.jena.query.ResultSet in project jena by apache.

the class FusekiConfig method servicesAndDatasets.

private static List<DataAccessPoint> servicesAndDatasets(Model model) {

    List<DataAccessPoint> accessPoints = new ArrayList<>();
    if (!rs.hasNext())
        // No "fu:services ( .... )" so try looking for services directly.
        // This means Fuseki2, service configuration files (no server section) work for --conf. 
        rs = FusekiLib.query("SELECT ?service { ?service a fu:Service }", model);
    for (; rs.hasNext(); ) {
        QuerySolution soln = rs.next();
