Synopsis

choose(traversal,choice\_1,choice\_2,choice\_3)

Description

The choose() step is a branch step that can be used to route a traverser to a particular traversal branch, similar to if-then-else logic.

Examples

g.V().hasLabel('store').as('store').
  V().hasLabel('ingredient').as('ingredient').
  choose(where(__.in('isStockedWith').as('store')),
           constant('Y'), constant('N')).as('in stock').
  select('store','ingredient','in stock').
    by('name').
    by('name').
    by()
