How to send a message to an actor's parent in Akka Classic?

Question

What is the method for an actor to send a message to its parent?

I'm using Akka 2.2

Answer 1

You are looking for

getContext().parent() 

which gives you the ActorRef of the parent, so you can do

getContext().parent().tell(...) 

Answer 2

With Akka 2.4, you have to do context.parent inside an actor to have its parent actor reference. After that, you can send it a message as before (context.parent ! "hello").
