GroupSideEffectStep<S,K,V> |
clone()
Cloning is used to duplicate steps for the purpose of traversal optimization and OLTP replication.
|
Map<K,V> |
generateFinalResult(Map<K,?> object)
Post-process the side-effect and return the post-processed side-effect.
|
List<Traversal.Admin<?,?>> |
getLocalChildren() |
Set<TraverserRequirement> |
getRequirements()
Provide the necessary
TraverserRequirement that must be met by the traverser in order for the step to
function properly. |

prepareForProfiling()
Reset the
Barrier on the step to be wrapped in a ProfilingAware.ProfiledBarrier which can
properly start/stop the timer on the associated ProfileStep . |
