how to use Tinkerpop blueprints API in arangodb to get all vertices and edges

I have created graph and add vertices and edges using Tinkerpop api by using below code

ArangoDBBatchGraph arang = new ArangoDBBatchGraph("localhost", 8529, "testgraph", "testcollection", "testedgecollection");
        Vertex user = null;
        Vertex preVertex = null;
        preVertex = arang.addVertex(0);
        preVertex.setProperty("name", "edgevertex");

        long startTime = System.currentTimeMillis();
        for(int rec = 1; rec<=10; rec++) {

            user = arang.addVertex(rec);
            user.setProperty("name", "user"+ rec);
            user.setProperty("userid", rec);
            user.setProperty("gender", "male");
            user.setProperty("firstname", "user");
            user.setProperty("lastname", rec);
            user.setProperty("employee number", "emp0"+ rec);

            arang.addEdge(rec, user, preVertex, "edge"+ rec);
            preVertex = user;
        }

        System.out.println("write Time consumed : "+ (System.currentTimeMillis() - startTime));

but i want to get all the edges and vertices in the graph I tried below code, its not working throwing exception Exception in thread "main" java.lang.UnsupportedOperationException at com.arangodb.blueprints.batch.ArangoDBBatchGraph.getVertices(ArangoDBBatchGraph.java:277) at mydb.ArangodbTest.TestConnection.main(TestConnection.java:54)

startTime = System.currentTimeMillis();
        Iterable<Vertex>  iter = arang.getVertices();
        List<Vertex> list = new ArrayList<Vertex>();
        if(iter != null) {
            for(final Vertex vert : iter) {
                list.add(vert);
            }
        }
        Iterable<Edge>  iterEdge = arang.getEdges();
        List<Edge> listEdge = new ArrayList<Edge>();
        if(iter != null) {
            for(Edge edge : iterEdge) {
                listEdge.add(edge);
            }
        }

        System.out.println("Read vertices list: "+ list.size() + ", Edges List: "+listEdge+ "; Time consumed : "+ (System.currentTimeMillis() - startTime));

Please help to get all edges and vertices using tinkerpop api from arangodb

Thanks in advance

ArangoDBBatchGraph does not support the methods getVertices() and getEdges(). You have to use ArangoDBGraph instead of ArangoDBBatchGraph.

Apart from this your code should work.
