Class ScalaDSL.Widened<T,U>

java.lang.Object

akka.typed.Behavior<U>

akka.typed.ScalaDSL.Widened<T,U>

All Implemented Interfaces:

java.io.Serializable, scala.Equals, scala.Product

Enclosing class:

ScalaDSL

public static final class ScalaDSL.Widened<T,U>
extends Behavior<U>
implements scala.Product, scala.Serializable

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&rsquo;s type hierarchy. Signals are not transformed.

Method Detail

behavior

public Behavior<T> behavior()

matcher

public scala.PartialFunction<U,T> matcher()

management

public Behavior<U> management(ActorContext<U> ctx,
                              Signal msg)

Description copied from class: Behavior

Process an incoming Signal and return the next behavior. This means that all lifecycle hooks, ReceiveTimeout, Terminated and Failed messages can initiate a behavior change.

The returned behavior can in addition to normal behaviors be one of the canned special objects:

* returning Stopped will terminate this Behavior * returning Same designates to reuse the current Behavior * returning Unhandled keeps the same Behavior and signals that the message was not yet handled

Code calling this method should use Behavior$ canonicalize to replace the special objects with real Behaviors.

Specified by:

management in class Behavior<U>

Parameters:

ctx - (undocumented)

msg - (undocumented)

Returns:

(undocumented)

message

public Behavior<U> message(ActorContext<U> ctx,
                           U msg)
