Java GraphStorage.setSegmentSize示例

  @Test
  public void testCopyTo() {
    graph = createGraph();
    initExampleGraph(graph);
    GraphStorage gs = newRAMGraph();
    gs.setSegmentSize(8000);
    gs.create(10);
    try {
      graph.copyTo(gs);
      checkExampleGraph(gs);
    } catch (Exception ex) {
      ex.printStackTrace();
      assertTrue(ex.toString(), false);
    }

    try {
      Helper.close((Closeable) graph);
