使用Source.actorPublisher和FlowGraph时，在akka-stream 1.0中获取actorRef

Question

我的问题涉及到：Accessing the underlying ActorRef of an akka stream Source created by Source.actorRef 有一些差异：

1. 我正在使用akka-stream experimental 1.0
2. 我正在使用actorPublisher模型
3. 我正在使用FlowGraph dsl进行并行处理的流定义

我找不到让actorRef将消息发送到Source持有的Actor Publisher实例的方法。

 def run(implicit system: ActorSystem) = {
   import system.dispatcher
   implicit val materializer = ActorMaterializer()

   val source = Source.actorPublisher[TestRequest](TestActor.props).map { request => request.event }

   //Implementation in subpackage
   val sinkLevel1 = Sinks.sinkLevel1 
   val sinkLevel2 = Sinks.sinkLevel2

   //Implementation in subpackage
   val stageTriage = FlowStages.stageTriage    
   val stageEvalProcess1 = FlowStages.stageEvalProcess1
   val stageEvalProcess2 = FlowStages.stageEvalProcess2

   val pipeline = FlowGraph.closed(){ implicit builder => 
     import FlowGraph.Implicits._

     val stageDispatchByRuleLevels = builder.add(Broadcast[TriagedSystemEvent](2))

     source ~> stageTriage ~> stageDispatchByRuleLevels
                              stageDispatchByRuleLevels ~> stageEvalProcess1 ~> sinkLevel1
                              stageDispatchByRuleLevels ~> stageEvalProcess2 ~> sinkLevel2

   }

   pipeline.run()

 }

感谢您的帮助！

根据诺亚在链接问题中的回答，如果你添加

val ref = pipeline.run()

然后您可以向ref发送消息，例如

ref ! ...
