Examples with Resource org.apache.jena.rdf.model.Resource used on opensource projects

Example 11 with Resource

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

the class DatasetFactory method assemble.

/**
	 * Assemble a dataset from the model
	 *
	 * @param model
	 * @return Dataset
	 */
public static Dataset assemble(Model model) {
    Objects.requireNonNull(model, "model can not be null");
    Resource r = GraphUtils.findRootByType(model, DatasetAssembler.getType());
    if (r == null)
        throw new ARQException("No root found for type <" + DatasetAssembler.getType() + ">");
    return assemble(r);
}

Example 12 with Resource

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

the class DescribeBNodeClosure method describe.

// Check all named graphs
@Override
public void describe(Resource r) {
    // Default model.
    Closure.closure(otherModel(r, dataset.getDefaultModel()), false, acc);
    // Find all the named graphs in which this resource
    // occurs as a subject.  Faster than iterating in the
    // names of graphs in the case of very large numbers
    // of graphs, few of which contain the resource, in
    // some kind of persistent storage.
    QuerySolutionMap qsm = new QuerySolutionMap();
    qsm.add("s", r);
    QueryExecution qExec = QueryExecutionFactory.create(query, dataset, qsm);
    ResultSet rs = qExec.execSelect();
    for (; rs.hasNext(); ) {
        QuerySolution qs = rs.next();
        String gName = qs.getResource("g").getURI();
        Model model = dataset.getNamedModel(gName);
        Resource r2 = otherModel(r, model);
        Closure.closure(r2, false, acc);
    }
    //        // Named graphs
    //        for ( Iterator<String> iter = dataset.listNames() ; iter.hasNext() ; )
    //        {
    //            String name = iter.next();
    //            Model model =  dataset.getNamedModel(name) ;
    //            Resource r2 = otherModel(r, model) ;

Example 14 with Resource

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

the class TestFileManagerAssembler method testCreatesFileManagerWIthHandlers.

/**
        Can't just test for equality of locators list, since locators don't support
        equality. Weak hack: check that the sizes are the same. TODO improve.

    List<Locator> obtained = IteratorCollection.iteratorToList(f.locators());
    assertEquals(wanted.size(), obtained.size());
    assertEquals(wanted, obtained);
