trait Receive[T] extends Behavior[T]
Behavior
that exposes additional fluent DSL methods to further change the message or
signal reception behavior. It's returned by for example Behaviors.receiveMessage.

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).

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
