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()
