Message type which is sent directly to the subscribed actor in akka.actor.FSM.SubscribeTransitionCallback before sending any akka.actor.FSM.Transition messages.
Signifies that the akka.actor.FSM is shutting itself down because of an error, e.
Log Entry of the akka.actor.LoggingFSM, can be obtained by calling getLog
.
Reason why this akka.actor.FSM is shutting down.
This captures all of the managed state of the akka.actor.FSM: the state name, the state data, possibly custom timeout, stop reason and replies accumulated while processing the last message.
Send this to an akka.actor.FSM to request first the akka.actor.CurrentState and then a series of akka.actor.Transition updates.
Message type which is used to communicate transitions between states to all subscribed listeners (use akka.actor.FSM.SubscribeTransitionCallback).
Unsubscribe from akka.actor.FSM.Transition notifications which was effected by sending the corresponding akka.actor.FSM.SubscribeTransitionCallback.
This extractor is just convenience for matching a (S, S) pair, including a reminder what the new state is.
Default reason if calling stop()
.
A partial function value which does not match anything and can be used to
“reset” whenUnhandled
and onTermination
handlers.
Reason given when someone was calling system.stop(fsm)
from outside;
also applies to Stop
supervision directive.
This case object is received in case of a state timeout.
