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

This example Akka source code file (StatsWorker.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 akka.io; I'm just trying to make examples easier to find. (For my Scala work, see my Scala examples and tutorials.)

The StatsWorker.scala Akka example source code

package sample.cluster.stats

import akka.actor.Actor

//#worker
class StatsWorker extends Actor {
  var cache = Map.empty[String, Int]
  def receive = {
    case word: String =>
      val length = cache.get(word) match {
        case Some(x) => x
        case None =>
          val x = word.length
          cache += (word -> x)
          x
      }

      sender() ! length
  }
