actors

package actors

A library that provides both asynchronous and synchronous messaging to allow for concurrent programming without explicit synchronization.

Guide

A detailed guide for the actors library is available http://www.scala-lang.org/docu/files/actors-api/actors_api_guide.html#.

Getting Started

A starting point for using the actors library would be Reactor, ReplyReactor, or Actor or their companion objects.

Visibility
  1. Public
  2. All

Type Members

  1. case class ! [a] (ch: Channel[a], msg: a) extends Product with Serializable

    Used to pattern match on values that were sent to some channel Chann by the current actor self.

  2. trait AbstractActor extends OutputChannel[Any] with CanReply[Any, Any]

  3. trait Actor extends AbstractActor with ReplyReactor with ActorCanReply with InputChannel[Any] with Serializable

    Provides lightweight, concurrent actors.

  4. trait CanReply [-T, +R] extends AnyRef

    Defines result-bearing message send operations.

  5. class Channel [Msg] extends InputChannel[Msg] with OutputChannel[Msg] with CanReply[Msg, Any]

    Provides a means for typed communication among actors.

  6. trait DaemonActor extends Actor

    Base trait for actors with daemon semantics.

  7. case class Exit (from: AbstractActor, reason: AnyRef) extends Product with Serializable

    Sent to an actor with trapExit set to true whenever one of its linked actors terminates.

  8. class Future [+T] extends Responder[T] with () ⇒ T

    A function of arity 0, returing a value of type T that, when applied, blocks the current actor (Actor.self) until the future's value is available.

  9. trait IScheduler extends AnyRef

    A common interface for all schedulers used to execute actor tasks.

  10. trait InputChannel [+Msg] extends AnyRef

    A common interface for all channels from which values can be received.

  11. trait OutputChannel [-Msg] extends AnyRef

    A common interface for all channels to which values can be sent.

  12. trait Reactor [Msg >: Null] extends OutputChannel[Msg] with Combinators

    Super trait of all actor traits.

  13. trait ReplyReactor extends Reactor[Any] with ReactorCanReply

    Extends the Reactor trait with methods to reply to the sender of a message.

  14. trait SchedulerAdapter extends IScheduler

    Adapts the behavior of the standard scala.actors.Scheduler object.

  15. case class UncaughtException (actor: Actor, message: Option[Any], sender: Option[OutputChannel[Any]], thread: Thread, cause: Throwable) extends Exception with Product with Serializable

    The exit reason when an actor fails to catch an exception.

  16. class Debug extends Logger

    this class is going to be removed in a future release

  17. type FJTaskScheduler2 = ForkJoinScheduler

    use scheduler.ForkJoinScheduler instead

  18. class MessageQueue extends MQueue[Any] with Serializable

    The class MessageQueue provides an efficient implementation of a message queue specialized for this actor library.

  19. class MessageQueueElement extends MQueueElement[Any] with Serializable

    This class is used by our efficient message queue implementation.

  20. class Reaction extends ActorTask

    The abstract class Reaction associates an instance of an Actor with a java.lang.Runnable.

Value Members

  1. object Actor extends Combinators with Serializable

    Provides functions for the definition of actors, as well as actor operations, such as receive, react, reply, etc.

  2. object Debug extends Logger

    Provides methods for generating debugging output.

  3. object Futures extends AnyRef

    Methods that operate on futures.

  4. object Scheduler extends DelegatingScheduler

    Used by Actor instances to execute tasks of an actor execution.

  5. object TIMEOUT extends Product with Serializable

    Used as the timeout pattern in receiveWithin and reactWithin.
