trait Act extends Actor

This trait provides a DSL for writing the inner workings of an actor, e.g. for quickly trying things out in the REPL. It makes the following keywords available:

  • become mapped to context.become(_, discardOld = true)
  • becomeStacked mapped to context.become(_, discardOld = false)
  • unbecome mapped to context.unbecome
  • setup for implementing preStart()
  • whenFailing for implementing preRestart()
  • whenRestarted for implementing postRestart()
  • teardown for implementing postStop

Using the life-cycle keywords multiple times results in replacing the content of the respective hook.
