Provides lightweight, concurrent actors.
Provides lightweight, concurrent actors. Actors are created by extending
the Actor trait (alternatively, one of the factory methods in its
companion object can be used). The behavior of an Actor subclass is
defined by implementing its act method:
class MyActor extends Actor { def act() { // actor behavior goes here } }
A new Actor instance is started by invoking its start method.
Note: care must be taken when invoking thread-blocking methods other
than those provided by the Actor trait or its companion object (such as
receive). Blocking the underlying thread inside an actor may lead to
starvation of other actors. This also applies to actors hogging their
thread for a long time between invoking receive/react.
If actors use blocking operations (for example, methods for blocking I/O), there are several options:
actors.corePoolSize JVM property).scheduler method of the Actor trait can be overridden to return a
ResizableThreadPoolScheduler, which resizes its thread pool to
avoid starvation caused by actors that invoke arbitrary blocking methods.actors.enableForkJoin JVM property can be set to false, in which
case a ResizableThreadPoolScheduler is used by default to execute actors.The main ideas of the implementation are explained in the two papers

Guide
A detailed guide for the actors library is available http://docs.scala-lang.org/overviews/core/actors.html.
Getting Started
A starting point for using the actors library would be scala.actors.Reactor, scala.actors.ReplyReactor, or scala.actors.Actor or their companion objects.
As of release 2.10.1, replaced by
akka.actorpackage. For migration of existing actors refer to the Actors Migration Guide.
