Examples with GraphTransaction com.baidu.hugegraph.backend.tx.GraphTransaction used on opensource projects

Example 21 with GraphTransaction

use of com.baidu.hugegraph.backend.tx.GraphTransaction in project incubator-hugegraph by apache.

the class VertexCoreTest method testAddVertexWithTx.

@Test
public void testAddVertexWithTx() {
    HugeGraph graph = graph();
    GraphTransaction tx = params().openTransaction();
    tx.addVertex(T.label, "book", "name", "java-4");
    tx.addVertex(T.label, "book", "name", "java-5");
    try {
        tx.commit();
    } finally {
        tx.close();
    }
    long count = graph.traversal().V().count().next();
    Assert.assertEquals(2, count);
}

Example 22 with GraphTransaction

use of com.baidu.hugegraph.backend.tx.GraphTransaction in project incubator-hugegraph by apache.

the class VertexCoreTest method testRemoveVertexAfterAddVertexWithTx.

@Test
public void testRemoveVertexAfterAddVertexWithTx() {
    HugeGraph graph = graph();
    GraphTransaction tx = params().openTransaction();
    Vertex java1 = tx.addVertex(T.label, "book", "name", "java-1");
    tx.addVertex(T.label, "book", "name", "java-2");
    tx.commit();
    java1.remove();
    tx.commit();
    tx.close();
    List<Vertex> vertices = graph.traversal().V().toList();
    Assert.assertEquals(1, vertices.size());
    assertNotContains(vertices, T.label, "book", "name", "java-1");
