Description
The inV() step moves the traversal to the incoming vertices.
Examples
Move to all incoming adjacent vertices for all the edges in the
graph:
g.E().inV().valueMap()Get all incoming incident edges for all vertices, then move to the incoming vertices that
have those incident edges:
g.V().inE('knows').inV().valueMap()Get all incoming incident edges for all vertices, then move to the incoming vertices that
have those incident edges and a vertex label
person:
g.V().inE('knows').inV().hasLabel('person')
