mid-traversal V()
Fetch a vertex in the middle of a graph traversal.
Synopsis
V().has('vertexLabel', 'propertyKey', 'propertyValue')
Description
A mid-traversal V() step can be used to fetch an additional vertex in the middle of a graph traversal, to use for some additional operation.
Examples
Use a mid-traversal V() to fetch the person named Sharon Smith, so that an edge can be created between Jim Walsh and Sharon Smith:
// graph step V() in mid-traversal
// create a new user to use in the addE() step named Jim Walsh
//g.addV('person').property('personId', 26).property('name','Jim Walsh').property('gender', 'M')
// use a mid-traversal V() step to create a new edge between two people
g.V().has('person', 'name', 'Jim Walsh').as('jim').
V().has('person', 'name', 'Sharon Smith').as('sharon').
addE('knows').from('jim').to('sharon').
property('since', 1980)
