Method Detail

initiateFaultToleranceOrTerminate

public static Activity.Status initiateFaultToleranceOrTerminate(Activity activity)

If this is not the last attempt, set the status to Status.FAILED and initiate fault tolerance, otherwise set Status.TERMINATED. As side effect, this method decreases the attempts variable and stores it back to as property to the input tokens and removes the failed operation candidate from the transition's operation.
