Examples with Dataset org.apache.jena.query.Dataset used on opensource projects

Example 1 with Dataset

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

the class sdbupdate method execCmd.

@Override
protected void execCmd(List<String> positionalArgs) {
    if (isVerbose())
        SDB_QC.PrintSQL = true;
    getStore();
    Dataset dataset = getModStore().getDataset();
    List<String> requestFiles = getValues(updateArg);
    if (requestFiles.size() == 0 && getPositional().size() == 0)
        throw new CmdException("Nothing to do");
    for (String filename : requestFiles) execOneFile(filename, dataset);
    for (String requestString : super.getPositional()) {
        requestString = indirect(requestString);
        execOne(requestString, dataset);
    }
}

Example 2 with Dataset

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

the class TestAssembler method dataset_1.

@Test
public void dataset_1() {
    Dataset ds = DatasetFactory.assemble(dir + "dataset.ttl");
    assertNotNull(ds);
    // Check it will be dispatched to SDB
    DatasetGraph dsg = ds.asDatasetGraph();
    assertTrue(dsg instanceof DatasetGraphSDB);
}

Example 3 with Dataset

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

the class TestAssembler method create.

private Store create(Model assem) {
    // Create a store and format
    Dataset ds = DatasetFactory.assemble(assem);
    Store store = ((DatasetGraphSDB) ds.asDatasetGraph()).getStore();
    store.getTableFormatter().create();
    return store;
}

Example 4 with Dataset

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

the class ExRIOT_out2 method main.

public static void main(String[] args) {
    Model model = RDFDataMgr.loadModel("D.ttl");
    System.out.println();
    System.out.println("#### ---- Write as TriG");
    System.out.println();
    // This wil be the default graph of the dataset written.
    RDFDataMgr.write(System.out, model, Lang.TRIG);
    // Loading Turtle as Trig reads into the default graph.
    Dataset dataset = RDFDataMgr.loadDataset("D.ttl");
    System.out.println();
    System.out.println("#### ---- Write as NQuads");
    System.out.println();
    RDFDataMgr.write(System.out, dataset, Lang.NQUADS);
}

Example 5 with Dataset

    StoreDesc desc = openStore(a, root, mode);
    Dataset ds = SDBFactory.connectDataset(desc);
    AssemblerUtils.setContext(root, ds.getContext());
    return ds;
}
