public interface GraphComputing

A GraphComputing step is one that will change its behavior whether its on a GraphComputer or not. ComputerFinalizationStrategy is responsible for calling the onGraphComputer() method. This method is only called for global children steps of a TraversalParent.

Method Summary

Modifier and Type	Method and Description
default void	atMaster(boolean atMaster) Some steps should behave different whether they are executing at the master traversal or distributed across the worker traversals.
static void	atMaster(Step<?,?> step, boolean atMaster)
void	onGraphComputer() The step will be executing on a GraphComputer.

Method Detail

onGraphComputer

void onGraphComputer()

The step will be executing on a GraphComputer.

atMaster

default void atMaster(boolean atMaster)

Some steps should behave different whether they are executing at the master traversal or distributed across the worker traversals. The default implementation does nothing.

Parameters:

atMaster - whether the step is currently executing at master

atMaster

static void atMaster(Step<?,?> step,
                     boolean atMaster)
