Provide easy helper methods that supports parameterized submission. about gremlinclient HOT 2 OPEN

Ah didn't read your code very closely. I've been crazy busy the last couple
weeks. The problem with the way your submit is implemented is that it will
only return the first result. In the case of a streaming response, it won't
work. So, you either have to collect the streaming response in a list and
return after the while loop is broken, or you have to use the while loop in
your application code and process the results one at a time. Make sense?

It took me a long time to realize to do this:

@gen.coroutine
def submit(gremlinServerURI, traversalString):
response = yield submit(gremlinServerURI, traversalString)
while True:
result = yield response.read()
if result is None:
break
raise gen.Return(result.data)

Where this is called via:

def toList(self):
return IOLoop.current().run_sync(lambda: Helper.submit(self.gremlinServerURI, self.traversalString))

For the following tutorial:

Be nice to provide such "easy" methods in gremlinclient.

To elaborate a bit, if you want to do everything in a coroutine and then return:

@gen.coroutine
def submit(gremlinServerURI, traversalString):
    output = []
    response = yield submit(gremlinServerURI, traversalString)
    while True:
        result = yield response.read()
        if result is None:
            break
        output.append(result.data)
    raise gen.Return(output)

But the a more typical use case is with a async Python framework, for example, with Tornado something like:

class MainHandler(tornado.web.RequestHandler):
    def get(self):
        response = yield submit(gremlinServerURI, traversalString)
        while True:
            result = yield response.read()
            if result is None:
                self.finish() 
            self.write(resp.data)
