Akka/Scala example source code file (ReceiveTimeout.scala)

This example Akka source code file (ReceiveTimeout.scala) is included in my "Source Code Warehouse" project. The intent of this project is to help you more easily find Akka and Scala source code examples by using tags.

All credit for the original source code belongs to; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

Akka tags/keywords

actor, actorcell, akka, cancel, cancellable, concurrent, duration, finiteduration, receivetimeout, time, unit

The ReceiveTimeout.scala Akka example source code

import ReceiveTimeout.emptyReceiveTimeoutData
import scala.concurrent.duration.Duration
import scala.concurrent.duration.FiniteDuration

private[akka] object ReceiveTimeout {
  final val emptyReceiveTimeoutData: (Duration, Cancellable) = (Duration.Undefined, ActorCell.emptyCancellable)

private[akka] trait ReceiveTimeout { this: ActorCell ⇒

  import ReceiveTimeout._
  import ActorCell._

  private var receiveTimeoutData: (Duration, Cancellable) = emptyReceiveTimeoutData

  final def receiveTimeout: Duration = receiveTimeoutData._1

  final def setReceiveTimeout(timeout: Duration): Unit = receiveTimeoutData = receiveTimeoutData.copy(_1 = timeout)

  final def checkReceiveTimeout() {
    val recvtimeout = receiveTimeoutData
    //Only reschedule if desired and there are currently no more messages to be processed
    if (!mailbox.hasMessages) recvtimeout._1 match {
      case f: FiniteDuration ⇒
        recvtimeout._2.cancel() //Cancel any ongoing future
        val task = system.scheduler.scheduleOnce(f, self,
        receiveTimeoutData = (f, task)
      case _ ⇒ cancelReceiveTimeout()
    else cancelReceiveTimeout()


  final def cancelReceiveTimeout(): Unit =
    if (receiveTimeoutData._2 ne emptyCancellable) {
      receiveTimeoutData = (receiveTimeoutData._1, emptyCancellable)
