Gremlin vertex with list properties

[michaelawarren]

I'm trying to create a property with a list of values. It looks like there is support for this DataTypes. This worked in Orient DB which ArcadeData says it is a fork of. Is there a way to make this work with gremlin queries.

g.addV().property(list, 'myList', ['a', 'b'])

Unbale to reproduce it. Tested this and works:

@Test
  public void testGremlinLists() throws ExecutionException, InterruptedException {
    final ArcadeGraph graph = ArcadeGraph.open("./target/testlist");
    try {
      final ResultSet result = graph.gremlin("g.addV('Person').property( 'list', ['a', 'b'] )").execute();

      Assertions.assertTrue(result.hasNext());
      final Result v = result.next();
      Assertions.assertTrue(v.isVertex());
      final List list = (List) v.getVertex().get().get("list");
      Assertions.assertEquals(2, list.size());
      Assertions.assertTrue(list.contains("a"));
      Assertions.assertTrue(list.contains("b"));

    } finally {
      graph.drop();
    }
  }

Ah i see what i was doing wrong. In orient db i was specifying the cardinality as the first value in properties(Cardnality.list, propertyname, propertyValue) (https://tinkerpop.apache.org/docs/current/reference/#addproperty-step). In arcade db this isn't necessary. Thank you for the quick responses.

Glad it worked out.
