Akka/Scala example source code file (Main2.scala)

This example Akka source code file (Main2.scala) is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Akka and Scala source code examples by using tags.

All credit for the original source code belongs to akka.io; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

The Main2.scala Akka example source code

package sample.hello

import akka.actor.ActorSystem
import akka.actor.Props
import akka.actor.ActorRef
import akka.actor.Actor
import akka.actor.ActorLogging
import akka.actor.Terminated

object Main2 {

  def main(args: Array[String]): Unit = {
    val system = ActorSystem("Hello")
    val a = system.actorOf(Props[HelloWorld], "helloWorld")
    system.actorOf(Props(classOf[Terminator], a), "terminator")
  }

  class Terminator(ref: ActorRef) extends Actor with ActorLogging {
    context watch ref
    def receive = {
      case Terminated(_) =>
        log.info("{} has terminated, shutting down system", ref.path)
        context.system.shutdown()
    }
  }
