Akka parent-child Actors example

As we discussed in the previous sections, Akka's ActorSystem creates all top-level actors, which may act as parent or supervisor Actors. So, how do we create subordinate Actors?

When we execute the ActorSystem.actorOf() function, it creates all top-level Actors. However, Akka Toolkit has provided an implicit variable, context of the ActorContext type in the Actor class, as follows:

trait Actor { 
   implicit val context: ActorContext = { 
     // Code goes here 
   } 
} 

Like ActorSystem.actorOf(),  the ActorSystem also has actorOf() with the same set of parameters to create child or subordinate Actors from a supervisor or parent Actor:

package com.packt.publishing.supervision 
import akka.actor.{Actor,Props,ActorSystem} 
 
sealed trait Work 
case object DevWork extends Work 
case object TestingWork extends Work 
class LeadDeveloperActor extends Actor{ 
  def receive = { 
    case DevWork => 
      val devActor = context.actorOf(Props[DevActor],"Dev") 
  ...
