extends AbstractActor with ReplyReactor with scala.actors.ReplyableActor

This class provides an implementation of event-based actors. The main ideas of our approach are explained in the two papers

Method Details
protected[actors] override def scheduler : IScheduler
def receive[R](f : PartialFunction[Any, R]) : R
Receives a message from this actor's mailbox.
Parameters
f - a partial function with message patterns and actions
Returns
result of processing the received value
def receiveWithin[R](msec : Long)(f : PartialFunction[Any, R]) : R
Receives a message from this actor's mailbox within a certain time span.
Parameters
msec - the time span before timeout
f - a partial function with message patterns and actions
Returns
result of processing the received value
override def react(f : PartialFunction[Any, Unit]) : Nothing
Receives a message from this actor's mailbox.

This method never returns. Therefore, the rest of the computation has to be contained in the actions of the partial function.

Parameters
f - a partial function with message patterns and actions
def reactWithin(msec : Long)(f : PartialFunction[Any, Unit]) : Nothing
Receives a message from this actor's mailbox within a certain time span.

This method never returns. Therefore, the rest of the computation has to be contained in the actions of the partial function.

Parameters
msec - the time span before timeout
f - a partial function with message patterns and actions
def ? : Any
Receives the next message from this actor's mailbox.
override def start : Actor
Starts this actor.
def link(to : AbstractActor) : AbstractActor
Links self to actor to.
Parameters
to - the actor to link to
Returns
the parameter actor
def link(body : => Unit) : Actor
Links self to the actor defined by body.
Parameters
body - the body of the actor to link to
Returns
the parameter actor
def unlink(from : AbstractActor) : Unit
Unlinks self from actor from.
protected[actors] 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.

protected[actors] override def exit : Nothing
Terminates with exit reason 'normal.
