It's easy to do that by mistake, for example:
class ActorA extends Actor {
def receive = {
case "hi" =>
// THIS IS A BUG
context.actorOf(Props(new ActorB(sender())))
}
}
The safe convention:
class ActorA extends Actor {
def receive = {
case "hi" =>
context.actorOf(ActorB.props(sender()))
}
}
object ActorB {
def props(replyTo: ActorRef): Props =
new Props(new ActorB(replyTo))
}
