Gremlin InMemory Client on TinkerGraph

Question

In my java project, I can create in-memory "GraphTraversalSource" and I can create traversal queries easily. But I wonder how can I create script queries like client.submit(query)?

public GraphTraversalSource gremlinGraph()
{
    final Graph graph = TinkerGraph.open();
    return graph.traversal();
}

I need a create Client object from TinkerGraph. Then I want to call client.submit(query) queries.

Is there any suggestion?

I'd say that the easiest way is to reference the gremlin-groovy module and create a GremlinGroovyScriptEngine instance (source code). Then you can just do:

Graph graph = TinkerGraph.open();
ScriptEngine engine = new GremlinGroovyScriptEngine();
Bindings b = new SimpleBindings();
b.put("g", graph);
Traversal t = (Traversal) engine.eval("g.V()", b);

Note that client.submit() is meant to submit Gremlin to a Gremlin Server compliant system. To use TinkerGraph in that context would mean hosting TinkerGraph in Gremlin Server.
