Value Summary
val tl : ThreadLocal
Method Summary
def ? : Any
Receives the next message from the mailbox of the current actor self.
def actor (body : => Unit) : Actor

This function is used for the definition of actors.

The following example demonstrates its usage:

   import scala.actors.Actor._
   ...
   val a = actor {
     ...
   }
   
def continue : Unit
def eventloop (f : PartialFunction[Any, Unit]) : Nothing
def exit : Nothing

Terminates execution of self with the following effect on linked actors:

For each linked actor a with trapExit set to true, send message Exit(self, 'normal) to a.

def exit (reason : AnyRef) : Nothing

Terminates execution of self with the following effect on linked actors:

For each linked actor a with trapExit set to true, send message Exit(self, reason) to a.

For each linked actor a with trapExit set to false (default), call a.exit(reason) if reason != 'normal.

def link (to : Actor) : Actor
Links self to actor to.
def link (body : => Unit) : Actor
Links self to actor defined by body.
def loop (body : => Unit) : Nothing
Causes self to repeatedly execute body.
implicit def mkBody [a](body : => a) : Body[a]
def react (f : PartialFunction[Any, Unit]) : Nothing
Lightweight variant of receive. Actions in f have to contain the rest of the computation of self, as this method will never return.
def reactWithin (msec : Long)(f : PartialFunction[Any, Unit]) : Nothing
Lightweight variant of receiveWithin. Actions in f have to contain the rest of the computation of self, as this method will never return.
def receive [A](f : PartialFunction[Any, A]) : A
Receives a message from the mailbox of self. Blocks if no message matching any of the cases of f can be received.
def receiveWithin [R](msec : Long)(f : PartialFunction[Any, R]) : R
Receives a message from the mailbox of self. Blocks at most msec milliseconds if no message matching any of the cases of f can be received. If no message could be received the TIMEOUT action is executed if specified.
def reply : Unit
Send () to the actor waiting in a call to !?.
def reply (msg : Any) : Unit
Send msg to the actor waiting in a call to !?.
def resetProxy : Unit
Resets an actor proxy associated with the current thread. It replaces the implicit ActorProxy instance of the current thread (if any) with a new instance. This permits to re-use the current thread as an actor even if its ActorProxy has died for some reason.
def self : Actor
Returns the currently executing actor. Should be used instead of this in all blocks of code executed by actors.
def sender : OutputChannel[Any]
Returns the actor which sent the last received message.
def unlink (from : Actor) : Unit
Unlinks self from actor from.
