--------------------------------------
Summary: Add a .toGremlinGroovyString() method to Traversal class
Key: TINKERPOP-2050
URL: https://issues.apache.org/jira/browse/TINKERPOP-2050
Project: TinkerPop
Issue Type: Improvement
Reporter: Jim Hatcher
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.
