Creating a RoundRobinPool of actors

In this recipe, you will learn how to create a RoundRobinPool for actors. A RoundRobinPool is a group of the same type of actors and resembles the property whereby messages are delivered one by one to all the actors in the loop. In RoundRobinPool, all the actors share the same mailbox.

Getting ready

To step through this recipe, you will have to import the Hello-Akka project in the IDE.

How to do it...

1. Create a Scala file, RoundRobin.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.RoundRobinPool 

3. Let's define an actor as follows:

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

 

4. Let's create a test application:

        object RoundRobinPoolApp...
