Akka FSM Goto 10 FTW!

gistfile1.scala

class GotoFsm extends Actor with FSM[Int, Null] {

  notifying {
    case Transition(_, 10) => println("Goto 10 ftw!")
  }

  when(0) {
    case _ => goto(10) until 5000
  }

  when(10) {
    case _ => stop
  }

  startWith(0, null)

  onTermination {
    case _ => println("Bye bye :-)")
  }
}

case object Go
object GotoFsm {
  def main(args: Array[String]) {

    val gotoFsm = Actor.actorOf[GotoFsm].start

    gotoFsm !! Go
  }
}

Cool. Add it to the akka docs.

() / Unit is a touch more idiomatic Scala than null / Null. Otherwise, I like!
