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
