------------------------------------
Summary: GraphSONMessageSerializerV2d0 fails to deserialize valid
P.not()
Key: TINKERPOP-1894
URL: https://issues.apache.org/jira/browse/TINKERPOP-1894
Project: TinkerPop
Issue Type: Bug
Affects Versions: 3.3.1, 3.2.7
Reporter: Jorge Bay
GraphSONMessageSerializerV2d0 is not able to deserialize a g:P predicate for
not.
You can use the following test to reproduce it:
{code:java}
public class GraphSONMessageSerializerV2d0Test {
// ...
@Test
public void shouldDeserializeNotPredicate() throws Exception {
final RequestMessage m =
SERIALIZER.deserializeRequest("{\"requestId\":{\"@type\":\"g:UUID\",\"@value\":\"0397b9c0-ffab-470e-a6a8-644fc80c01d6\"},\"op\":\"bytecode\",\"processor\":\"traversal\",\"args\":{\"gremlin\":{\"@type\":\"g:Bytecode\",\"@value\":{\"step\":[[\"V\"],[\"hasLabel\",\"person\"],[\"has\",\"age\",{\"@type\":\"g:P\",\"@value\":{\"predicate\":\"not\",\"value\":{\"@type\":\"g:P\",\"@value\":{\"predicate\":\"lte\",\"value\":{\"@type\":\"g:Int32\",\"@value\":10}}}}}]]}},\"aliases\":{\"g\":\"gmodern\"}}}");
assertEquals("bytecode", m.getOp());
assertNotNull(m.getArgs());
}
}
{code}
