Examples
Get all outgoing adjacent vertices for all the edges in the
graph:
g.E().outV().valueMap()Get all outgoing incident edges for all vertices, then move to the incoming vertices that
have those incident edges:
g.V().outE('knows').inV().valueMap()Get all outgoing incident edges for all vertices, then move to the incoming vertices that
have those incident edges and a vertex label
person:
g.V().outE('knows').inV().hasLabel('person')
