Behavior that exposes additional fluent DSL methods to further change the message or signal reception behavior. It's returned by for example Behaviors.receiveMessage.

Abstract Value Members

  1. abstract def receiveSignal(onSignal: PartialFunction[(ActorContext[T], Signal), Behavior[T]]): Behavior[T]

Concrete Value Members

  1. val behavior: Behavior[T]
    Implicit
    This member is added by an implicit conversion from Receive[T] to BehaviorDecorators[T] performed by method BehaviorDecorators in akka.actor.typed.Behavior.

  2. final def narrow[U <: T]: 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).

  3. final def orElse(that: Behavior[T]): Behavior[T]

    Composes this Behavior with a fallback Behavior which is used when this Behavior doesn't handle the message or signal, i.e. when unhandled is returned.

  4. def widen[U](matcher: PartialFunction[U, T]): Behavior[U]

    Widen the wrapped Behavior by placing a funnel in front of it: 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.

    Widen the wrapped Behavior by placing a funnel in front of it: 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:

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

    Scheduled messages via akka.actor.typed.scaladsl.TimerScheduler can currently not be used together with widen, see issue #25318.
