Find all source vertices?

[jaufderheide]

Trying to retrieve source vertices from the CosmosDb graph. The Gremlin query is just:

g.V().not(inE())

So get all vertices with no incoming edges.

Cant figure out what Gremlinq expects inside Not(); its not used in the examples as far as I have found.

TIA if anyone can point me in the right direction! Sorry if this is a dumb question; I've been searching without much luck.

There's tons of usage examples in the unit tests, such as this one.

Thank you! Easy enough. Didn't think to look at the tests, probably a sad comment on my development experience ;)
