Example 76 with Resource

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

the class TestConcurrentAccess method mrswGraph4.

@Test(expected = ConcurrentModificationException.class)
public void mrswGraph4() {
    Model m = create().getDefaultModel();
    Resource r = m.createResource("x");
    ExtendedIterator<Statement> iter1 = m.listLiteralStatements(r, null, 1);
    assertNotNull(iter1.next());
    // and now the iterator has implicitly finished.
    Triple t = SSE.parseTriple("(<y> <p> 99)");
    m.getGraph().add(t);
    // Bad - modification of the dataset occurred.
    iter1.hasNext();
}

Example 77 with Resource

    ExtendedIterator<Statement> iter1 = m.listStatements(r, null, (RDFNode) null);
    assertNotNull(iter1.next());

Example 78 with Resource

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

the class RDFOutput method asRDF.

public Resource asRDF(Model model, boolean result) {
    Resource results = model.createResource();
    results.addProperty(RDF.type, ResultSetGraphVocab.ResultSet);
    Literal lit = model.createTypedLiteral(result);
    results.addProperty(ResultSetGraphVocab.p_boolean, lit);
    return results;
}

Example 79 with Resource

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

the class TestJsonLDWriter method testContextByUri.

/**
     * Checks that one can pass a context defined by its URI
     * 
     * -- well NO, this doesn't work
     */
@Test
public final void testContextByUri() {
    Model m = ModelFactory.createDefaultModel();
    String ns = "http://schema.org/";
    Resource s = m.createResource();
    m.add(s, m.createProperty(ns + "name"), "Jane Doe");
    m.add(s, m.createProperty(ns + "url"), "http://www.janedoe.com");
    m.add(s, RDF.type, "Person");
    // we can pass an uri in the context, as a quoted string (it is a JSON string)
    JsonLDWriteContext jenaContext = new JsonLDWriteContext();
    try {
        jenaContext.set(JsonLDWriter.JSONLD_CONTEXT, "{\"@context\" : \"http://schema.org/\"}");
        String jsonld = toString(m, RDFFormat.JSONLD, jenaContext);
        // check it parses ok
        Model m2 = parse(jsonld);
    // assertTrue(m2.isIsomorphicWith(m)); // It should be the case, but no.
    } catch (Throwable e) {
        // maybe test run in a setting wo external connectivity - not a real problem
        String mess = e.getMessage();
        if ((mess != null) && (mess.contains("loading remote context failed"))) {
            Logger.getLogger(getClass()).info(mess);
            e.printStackTrace();
        } else {
            throw e;
        }
    }
// But anyway, that's not what we want to do:
// there's no point in passing the uri of a context to have it dereferenced by jsonld-java
// (this is for a situation where one would want to parse a jsonld file containing a context defined by a uri)
// What we want is to pass a context to jsonld-java (in order for json-ld java to produce the correct jsonld output)
// and then we want to replace the @context in the output by "@context":"ourUri"
// How would we do that? see testSubstitutingContext()
