Interface LoggingPersistentFSM<S,D,E>

All Superinterfaces:

Actor, ActorLogging, Listeners, PersistentFSMBase<S,D,E>

All Known Implementing Classes:

AbstractPersistentLoggingFSM

public interface LoggingPersistentFSM<S,D,E>
extends PersistentFSMBase<S,D,E>

Stackable trait for FSM which adds a rolling event log and debug logging capabilities (analogous to LoggingReceive).

This is an EXPERIMENTAL feature and is subject to change until it has received more real world testing.

Method Detail

logDepth

int logDepth()

debugEvent

boolean debugEvent()

Specified by:

debugEvent in interface PersistentFSMBase<S,D,E>

advance

void advance()

processEvent

void processEvent(PersistentFSM.Event<D> event,
                  java.lang.Object source)

Specified by:

processEvent in interface PersistentFSMBase<S,D,E>

getLog

scala.collection.IndexedSeq<PersistentFSM.LogEntry<S,D>> getLog()

Retrieve current rolling log in oldest-first order. The log is filled with each incoming event before processing by the user supplied state handler. The log entries are lost when this actor is restarted.

Returns:

(undocumented)
