Creating a BroadcastPool of actors

In some situations, we may want to send the same message to all the actors. Here is a BroadcastPool that lets us do so. It can be used when we want to send a common command to all the actors to do the same work.

Getting ready

Just import the Hello-Akka project in the IDE; the other prerequisites are the same as before.

How to do it...

1. Create a Scala file, Broadcastpool.scala, in the package com.packt.chapter3.
2. Add the following imports to the top of the file:

        import akka.actor.{Props, ActorSystem, Actor} 
        import akka.routing.BroadcastPool 

3. Define a simple actor as an example:

        class BroadcastPoolActor extends Actor { 
          override def receive = { 
            case msg: String => println(s" $msg, I am 
             ${self.path.name}") 
            case _ => println(s" I don't understand the message") 
          } 
        } 

4. Create a simple test application as follows:

        object Broadcastpool extends App { 
          val actorSystem...
