Abstract Value Members

  1. abstract def apply(ctx: TypedActorContext[Command]): Behavior[Command]
    Definition Classes
    DeferredBehavior
  2. abstract def onPersistFailure(backoffStrategy: BackoffSupervisorStrategy): DurableStateBehavior[Command, State]

    Back off strategy for persist failures.

    Back off strategy for persist failures.

    Specifically BackOff to prevent resume being used. Resume is not allowed as it will be unknown if the state has been persisted.

    This supervision is only around the DurableStateBehavior not any outer setup/withTimers block. If using restart, any actions e.g. scheduling timers, can be done on the PreRestart

    If not specified the actor will be stopped on failure.

  3. abstract def persistenceId: PersistenceId
  4. abstract def receiveSignal(signalHandler: PartialFunction[(State, Signal), Unit]): DurableStateBehavior[Command, State]

    Allows the DurableStateBehavior to react on signals.

    Allows the DurableStateBehavior to react on signals.

    The regular lifecycle signals can be handled as well as DurableStateBehavior specific signals (recovery related). Those are all subtypes of pekko.persistence.typed.state.DurableStateSignal

  5. abstract def signalHandler: PartialFunction[(State, Signal), Unit]

    returns

    The currently defined signal handler or an empty handler if no custom handler previously defined

  6. abstract def snapshotAdapter(adapter: SnapshotAdapter[State]): DurableStateBehavior[Command, State]

    Transform the state to another type before giving to the store.

    Transform the state to another type before giving to the store. Can be used to transform older state types into the current state type e.g. when migrating from Persistent FSM to Typed DurableStateBehavior.

  7. abstract def withDurableStateStorePluginId(id: String): DurableStateBehavior[Command, State]

    Change the DurableStateStore plugin id that this actor should use.

  8. abstract def withTag(tag: String): DurableStateBehavior[Command, State]

    The tag that can used in persistence query

  18. final def narrow[U <: Command]: Behavior[U]

    Narrow the type of this Behavior, which is always a safe operation.

    Narrow the type of this Behavior, which is always a safe operation. This method is necessary to implement the contravariant nature of Behavior (which cannot be expressed directly due to type inference problems).

  24. def transformMessages[Outer](matcher: PartialFunction[Outer, Command])(implicit arg0: ClassTag[Outer]): Behavior[Outer]

    Transform the incoming messages by placing a funnel in front of the wrapped Behavior: the supplied PartialFunction decides which message to pull in (those that it is defined at) and may transform the incoming message to place them into the wrapped Behavior’s type hierarchy.

    Transform the incoming messages by placing a funnel in front of the wrapped Behavior: the supplied PartialFunction decides which message to pull in (those that it is defined at) and may transform the incoming message to place them into the wrapped Behavior’s type hierarchy. Signals are not transformed.

    Example:

    val b: Behavior[Number] =
      Behaviors
        .receive[String] { (ctx, msg) =>
          println(msg)
          Behaviors.same
        }
        .transformMessages[Number] {
          case b: BigDecimal => s"BigDecimal($b)"
          case i: BigInt     => s"BigInteger($i)"
          // all other kinds of Number will be `unhandled`
        }

    The ClassTag for Outer ensures that only messages of this class or a subclass thereof will be intercepted. Other message types (e.g. a private protocol) will bypass the interceptor and be continue to the inner behavior untouched.
