Example 1 with Graph

use of org.apache.jena.graph.Graph in project jena by apache.

the class TestConnectionPooled method reuseJDBCConection.

@Test

    Triple t1 = SSE.parseTriple("(:x1 :p :z)");
    Triple t2 = SSE.parseTriple("(:x2 :p :z)");
    boolean explicitTransactions = false;
    // Make store.
    {

        Store store1 = StoreFactory.create(sConn1, store.getLayoutType(), store.getDatabaseType());
        if (explicitTransactions)
            store1.getConnection().getTransactionHandler().begin();
        Graph graph1 = SDBFactory.connectDefaultGraph(store1);

        assertTrue(graph1.contains(t1));
        if (explicitTransactions) {
            store1.getConnection().getTransactionHandler().commit();
            assertTrue(graph1.contains(t1));
        }
    //store1.close() ;
    }
    // Mythically return conn to the pool.
    // Get from pool
    // i.e. same connection.  Make a store around it
    {
        SDBConnection sConn2 = SDBConnectionFactory.create(conn);
        Store store2 = StoreFactory.create(sConn2, store.getLayoutType(), store.getDatabaseType());
        if (explicitTransactions)
            store2.getConnection().getTransactionHandler().begin();
        Graph graph2 = SDBFactory.connectDefaultGraph(store2);
        assertTrue(graph2.contains(t1));
        graph2.add(t2);
        assertTrue(graph2.contains(t2));
        if (explicitTransactions)
            store2.getConnection().getTransactionHandler().commit();
    //store2.close() ;
    }
    System.exit(0);
}

    assertTrue(graph.isIsomorphicWith(graph1));
}

Example 4 with Graph

use of org.apache.jena.graph.Graph in project jena by apache.

the class GraphMakerContractTest method testListAfterDelete.

/**
	 * Test that a maker with some things put in and then some removed gets the
	 * right things listed.
	 */
@ContractTest
public void testListAfterDelete() {
    String x = "x_y", y = "y//zub", z = "a:b/c";
    Graph X = graphMaker.createGraph(x);

}

Example 5 with Graph

use of org.apache.jena.graph.Graph in project jena by apache.

the class GraphMakerContractTest method testGetGraph.

/**
	 * Foo trivial test that getGraph delivers a proper graph, not cheating with
	 * null, and that getGraph() "always" delivers the same Graph.
	 */

    Graph g1 = graphMaker.getGraph();
    assertFalse("should deliver a Graph", g1 == null);
    assertSame(g1, graphMaker.getGraph());
