Changes the Actor's behavior to become the new 'Receive' (PartialFunction[Any, Unit]) handler.
Changes the Actor's behavior to become the new 'Receive' (PartialFunction[Any, Unit]) handler. Puts the behavior on top of the hotswap stack. If "discardOld" is true, an unbecome will be issued prior to pushing the new behavior to the stack

To be implemented by concrete UntypedActor.
To be implemented by concrete UntypedActor. Defines the message handler.
User overridable callback.
User overridable callback.
Is called right AFTER restart on the newly created Actor to allow reinitialization after an Actor crash.
User overridable callback.
User overridable callback.
Is called when 'actor.stop()' is invoked.
User overridable callback.
User overridable callback.
Is called on a crashed Actor right BEFORE it is restarted to allow clean up of resources before Actor is terminated.
User overridable callback.
User overridable callback.
Is called when an Actor is started by invoking 'actor.start()'.
User overridable callback/setting.
User overridable callback/setting.
Partial function implementing the actor logic. To be implemented by concrete actor class.
Example code:
def receive = {
case Ping =>
println("got a 'Ping' message")
self.reply("pong")
case OneWay =>
println("got a 'OneWay' message")
case unknown =>
println("unknown message: " + unknown)
}
The 'self' field holds the ActorRef for this actor.
The 'self' field holds the ActorRef for this actor.
Can be used to send messages to itself:
self ! messageHere you also find most of the Actor API.
For example fields like:
self.dispatcher = ... self.trapExit = ... self.faultHandler = ... self.lifeCycle = ... self.sender
Here you also find methods like:
self.reply(..) self.link(..) self.unlink(..) self.start(..) self.stop(..)

Reverts the Actor behavior to the previous one in the hotswap stack.
User overridable callback.
User overridable callback.
Is called when a message isn't handled by the current behavior of the actor by default it throws an UnhandledMessageException
An UntypedDispatcher is an abstract class whose purpose is to route incoming messages to actors.
