Description
The both() step moves the traversal to both the outgoing and the incoming
adjacent vertices, given the edge labels. Specifying no edge label will traverse all
incident edges.
Examples
Get all outgoing and incoming adjacent vertices for all the vertices in the
graph:
g.V().both().valueMap()Get all outgoing and incoming adjacent vertices for all the vertices with incident edges
knows:
g.V().both('knows).valueMap()
