public class ActorDSL$ extends java.lang.Object implements Inbox, Creators
For the communication of non-actor code with actors, you may use anonymous actors tailored to this job:
import ActorDSL._
import scala.concurrent.util.duration._
implicit val system: ActorSystem = ...
implicit val i = inbox()
someActor ! someMsg // replies will go to `i`
val reply = i.receive()
val transformedReply = i.select(5 seconds) {
case x: Int => 2 * x
}
The receive and select methods are synchronous, i.e. they block the
calling thread until an answer from the actor is received or the timeout
expires. The default timeout is taken from configuration item
akka.actor.dsl.default-timeout.
When defining actors in the REPL, say, you may want to have a look at the
Act trait:
import ActorDSL._
val system: ActorSystem = ...
val a = actor(system, "fred")(new Act {
val b = actor("barney")(new Act {
...
})
become {
case msg => ...
}
})
Note that actor can be used with an implicit ActorRefFactory
as shown with "barney" (where the ActorContext serves this
purpose), but since nested declarations share the same
lexical context "fred"’s ActorContext would be ambiguous
if the ActorSystem were declared implicit (this could also
be circumvented by shadowing the name system within "fred").
Note: If you want to use an Act with Stash, you should use the
ActWithStash trait in order to have the actor get the necessary deque-based
mailbox setting.
