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')
