How to exit a Scala Actor (exit, quit, or terminate an Actor)

While working with a Scala Actor last night, I came across a situation where I wanted to be able to manually tell the Actor to quit/die/terminate.

It looks like the proper way to exit a Scala Actor is pretty simple:

  1. Send a message to the Actor telling it you want it to stop.
  2. The Actor calls the exit function on itself.

I could write more about this, but I think the answer is easy enough to find on this page on the website. Just search that page for "exit", and you'll see that all they do is get some kind of message in their Actor's act/receive loop, then call exit().

Finally, although it's not too helpful, here's a link to the Scala Actor Exit class, technically a case class.
