final case class ReceiveMessage[Message]() extends Keyword[ReceiveMessage[Message], Message] with Product with Serializable

A keyword to receive next message of an Akka actor.

Installation

This ReceiveMessage keyword supports !-notation, which requires BangNotation and ResetEverywhere compiler plugins along with this receivemessage library. For sbt, add the following settings to your build.sbt:

addCompilerPlugin("com.thoughtworks.dsl" %% "compilerplugins-bangnotation" % "latest.release")
addCompilerPlugin("com.thoughtworks.dsl" %% "compilerplugins-reseteverywhere" % "latest.release")
libraryDependencies += "com.yang-bo.dsl.keywords.akka.actor" %% "receivemessage" % "latest.release"

Message

The type of message being received, which must be Any for akka.actor.Actor, and must be the same type of T for akka.actor.typed.Behavior.

Source
ReceiveMessage.scala
Example:

  1. This ReceiveMessage keyword can be used in the akka.actor.Actor.Receive domain, to receive the next message. The above code creates an actor to echo any messages.

    import akka.actor._
def echoActor = new Actor {
  def receive: Receive = {
    while (true) {
      val lastMessage = !ReceiveMessage[Any]
      sender() ! lastMessage
    }
    throw new Exception("Unreachable code!")
  }
}

val pinger = system.actorOf(Props(echoActor))
pinger ! "hello world"
expectMsg("hello world")
See also
