repeat

Loop until a condition is met.

Synopsis

repeat(traversal)

Description

The repeat() step is a branch step and is used for looping over a traversal to some given break predicate. Three step modulators can be used with the repeat() step, emit(), times(), or until().

Examples

Repeatedly gets the outgoing vertex, three times, and prints the results:

g.V().hasLabel('fridgeSensor').repeat(out()).times(3).valueMap()

A more complex example that repeats through all the outgoing knows adjacent vertices of John Doe:

g.V().hasLabel('person','name','John Doe').
  repeat(out('knows').dedup().
         aggregate('x').
           by(project('person','level').
                by('name').
                by(loops())
           )
    ).
    until(__.not(out('knows').simplePath())).
  cap('x').next()
