Easiest Way to Get List Cardinality Properties As a List?
What is the easiest way to retrieve the vertex properties that have list cardinality back as a list in the traversal stream? The values() step seems to unfold the list.
For example, using the "the crew" example graph.
I want something like the following:
Is there a more direct way than

after some reflection i sense that the question you are asking is actually the answer in the first place. i assume this is in relation to string/list functions, in which case use of
