Package org.graphwalker.core.machine

Class ReplayMachine

java.lang.Object

org.graphwalker.core.machine.MachineBase

org.graphwalker.core.machine.SimpleMachine

org.graphwalker.core.machine.ReplayMachine

All Implemented Interfaces:

Observable, Machine

public class ReplayMachine
extends SimpleMachine

ReplayMachine

ReplayMachine can re-run an previous executed path..

The ReplayMachine takes a Profiler from a previous execution and will re-run that execution in the same order. The edges and vertices will called exactly the same order.

If the last element of the execution is an edge, the ReplayMachine will execute the target vertex as well.

A typical use case could be a test that encountered a failure, and now you want to execute that test and see iff it can reproduce that failure.
