Example 1 with VertexArrayList

use of org.janusgraph.graphdb.query.vertex.VertexArrayList in project janusgraph by JanusGraph.

the class VertexListTest method testLists.

@Test

    for (int i = 0; i < num; i++) {
        JanusGraphVertex v = tx.addVertex();
        vll.add(v);
        val.add(v);
