trait
Actor
extends
OutputChannel[Any]
This class provides (together with Channel
) an
implementation of event-based actors.
The main ideas of our approach are explained in the two papers

Method Summary | |
def
|
!
(msg : Any) : Unit
Sends
msg to this actor (asynchronous). |
def
|
!!
(msg : Any) : Future[Any]
Sends
msg to this actor and immediately
returns a future representing the reply value. |
def
|
!!
[A](msg : Any, f : PartialFunction[Any, A]) : Future[A]
Sends
msg to this actor and immediately
returns a future representing the reply value.
The reply is post-processed using the partial function
f . This also allows to recover a more
precise type for the reply value. |
def
|
!?
(msec : Long, msg : Any) : Option[Any]
Sends
msg to this actor and awaits reply
(synchronous) within msec milliseconds. |
def
|
!?
(msg : Any) : Any
Sends
msg to this actor and awaits reply
(synchronous). |
def
|
?
: Any
Receives the next message from this actor's mailbox.
|
abstract def
|
act
: Unit
The behavior of an actor is specified by implementing this
abstract method. Note that the preferred way to create actors
is through the
actor method
defined in object Actor . |
def
|
exit
: Nothing
Terminates with exit reason
'normal . |
def
|
exit (from : Actor, reason : AnyRef) : Unit |
def
|
exit
(reason : AnyRef) : Nothing
Terminates execution of
For each linked actor
For each linked actor |
def
|
exitLinked : Unit |
def
|
exitLinked (reason : AnyRef) : Unit |
def
|
forward
(msg : Any) : Unit
Forwards
msg to this actor (asynchronous). |
def
|
freshReplyChannel : Channel[Any] |
def
|
link
(body : => Unit) : Actor
Links
self to actor defined by body . |
def
|
link
(to : Actor) : Actor
Links
self to actor to . |
def
|
linkTo (to : Actor) : Unit |
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. |
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. |
def
|
receive
[R](f : PartialFunction[Any, R]) : R
Receives a message from this actor's mailbox.
|
def
|
receiveWithin
[R](msec : Long)(f : PartialFunction[Any, R]) : R
Receives a message from this actor's mailbox within a certain
time span.
|
def
|
reply
(msg : Any) : Unit
Replies with
msg to the sender. |
def
|
replyChannel : Channel[Any] |
def
|
send
(msg : Any, replyTo : OutputChannel[Any]) : Unit
Sends
msg to this actor (asynchronous) supplying
explicit reply destination. |
def
|
sender : OutputChannel[Any] |
def
|
start
: Actor
Starts this actor.
|
def
|
unlink
(from : Actor) : Unit
Unlinks
self from actor from . |
def
|
unlinkFrom (from : Actor) : Unit |
