stephen mallette updated TINKERPOP-2050:
----------------------------------------
Affects Version/s: 3.2.9
> Add a .toGremlinGroovyString() method to Traversal class
> --------------------------------------------------------
>
> Key: TINKERPOP-2050
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2050
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.2.9
> Reporter: Jim Hatcher
> Priority: Minor
>
> I am working on a project where there is Java code being written to dynamically generate
a Traversal based on a request coming in to an API. You can think of this as a "Traversal
Builder."
> The code looks something like this:
> {code:java}
> Traversal<Vertex, Vertex> traversal = g.V();
> if (request.searchByAddress == true) {
> traversal.hasLabel("address");
> if (request.address.addressLine1 != null){
> traversal.has("address_line_1", request.address.addressLine1)
> }
> }
> etc.
> {code}
> When that code is being debugged, a traversal.toString() is run on the traversal to see
the ouptut. This output is Gremlin bytecode.
> It would be nice to have a way to easily see the Gremlin Groovy that was built so that
you could take the Groovy, drop it into Studio, make sure it runs, run a profile() on it,
and make sure it's efficient.
> I figured out that you can do this by running this code:
> {code:java}
> private String toGremlinGroovyString(Traversal traversal){
> if (traversal == null){
> return null;
> }
> Bytecode bc = traversal.asAdmin().getBytecode();
> return GroovyTranslator.of("g").translate(bc);
> }
> {code}
> I think it would be nice to add that as a method on the Traversal class so that it could
be used by driver users more easily.
