the message to send
Sends msg to this actor and immediately returns a future representing
the reply value.

the reply value.
the message to be sent
the future
Sends msg to this actor and immediately returns a future representing
the reply value.
Sends msg to this actor and immediately returns a future representing
the reply value. The reply is post-processed using the partial function
handler. This also allows to recover a more precise type for the reply
value.

Terminates execution of self with the following

Provides lightweight, concurrent actors. Actors are created by extending the
Actortrait (alternatively, one of the factory methods in its companion object can be used). The behavior of anActorsubclass is defined by implementing itsactmethod:A new
Actorinstance is started by invoking itsstartmethod.Note: care must be taken when invoking thread-blocking methods other than those provided by the
Actortrait or its companion object (such asreceive). 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 invokingreceive/react.If actors use blocking operations (for example, methods for blocking I/O), there are several options:
actors.corePoolSizeJVM property).schedulermethod of theActortrait can be overridden to return aResizableThreadPoolScheduler, which resizes its thread pool to avoid starvation caused by actors that invoke arbitrary blocking methods.actors.enableForkJoinJVM property can be set tofalse, in which case aResizableThreadPoolScheduleris used by default to execute actors.The main ideas of the implementation are explained in the two papers
(Since version 2.11.0) Use the akka.actor package instead. For migration from the scala.actors package refer to the Actors Migration Guide.
