Accessing the underlying ActorRef of an akka stream Source created by Source.actorRef

Question

I\'m trying to use the Source.actorRef method to create an akka.stream.scaladsl.Source object. Something of the form

import akka.stream.OverflowStrategy.fai         


        

Answer 1

As @Noah points out the experimental nature of akka-streams, his answer might not work with the 1.0 release. I had to follow the example given by this example:

implicit val materializer = ActorMaterializer()
val (actorRef: ActorRef, publisher: Publisher[TweetInfo]) = Source.actorRef[TweetInfo](1000, OverflowStrategy.fail).toMat(Sink.publisher)(Keep.both).run()
actorRef ! TweetInfo(...)
val source: Source[TweetInfo, Unit] = Source[TweetInfo](publisher)
