Examples with DateTimeWithinPeriod org.apache.rya.api.functions.DateTimeWithinPeriod used on opensource projects

Example 1 with DateTimeWithinPeriod

use of org.apache.rya.api.functions.DateTimeWithinPeriod in project incubator-rya by apache.

the class QueryIT method dateTimeWithinNow.

@Test
public void dateTimeWithinNow() throws Exception {
    final ValueFactory vf = new ValueFactoryImpl();
    final DatatypeFactory dtf = DatatypeFactory.newInstance();
    FunctionRegistry.getInstance().add(new DateTimeWithinPeriod());
    final String sparql = "PREFIX fn: <" + FN.NAMESPACE + ">" + "SELECT ?event ?startTime WHERE { ?event <uri:startTime> ?startTime. " + "FILTER(fn:dateTimeWithin(?startTime, NOW(), 30, <" + OWLTime.SECONDS_URI + "> ))}";
    final ZonedDateTime zTime = ZonedDateTime.now();
    final String time = zTime.format(DateTimeFormatter.ISO_INSTANT);
    final ZonedDateTime zTime1 = zTime.minusSeconds(30);
    final String time1 = zTime1.format(DateTimeFormatter.ISO_INSTANT);
    final Literal lit = vf.createLiteral(dtf.newXMLGregorianCalendar(time));
    final Literal lit1 = vf.createLiteral(dtf.newXMLGregorianCalendar(time1));
    // Create the Statements that will be loaded into Rya.
    final Collection<Statement> statements = Sets.newHashSet(vf.createStatement(vf.createURI("uri:event1"), vf.createURI("uri:startTime"), lit), vf.createStatement(vf.createURI("uri:event2"), vf.createURI("uri:startTime"), lit1));
    // Create the expected results of the SPARQL query once the PCJ has been computed.
    final Set<BindingSet> expectedResults = new HashSet<>();
    final MapBindingSet bs = new MapBindingSet();
    bs.addBinding("event", vf.createURI("uri:event1"));
    bs.addBinding("startTime", lit);
    expectedResults.add(bs);
    // Verify the end results of the query match the expected results.
    runTest(sparql, statements, expectedResults, ExportStrategy.RYA);
}
