  19. final def narrow[U <: T]: Behavior[U]

    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).

  25. def transformMessages[Outer](matcher: PartialFunction[Outer, T])(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.
