Tinkerpop traversal to string

Is it possible to get from a traversal a gremlin request ready to use ? As JPA do with the log in debug level. For tinkerpop the debug give the traversal.toString() which is time consuming to transform in a request.

Solution

  • You can translate a traversal back into a textual form using the GroovyTranslator class from Apache TinkerPop.

    If you had a traversal defined as follows

     Traversal t = 
      g.V().has("airport","region","US-TX").
            local(values("code","city").
            fold());

    You can convert that back to a text string using

    String query;
query = GroovyTranslator.of("g").
        translate(t.asAdmin().getBytecode());
    
System.out.println("\nResults from GroovyTranslator on a traversal");
System.out.println(query);
