      public <Outer> Behavior<Outer> transformMessages(scala.PartialFunction<Outer,Inner> matcher, scala.reflect.ClassTag<Outer> evidence$1)
      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&rsquo;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(&dollar;b)"
         case i: BigInt     => s"BigInteger(&dollar;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.
