sender inside a future

Question

I have an actor which on receiving a message, searches the filesystem for a file and returns the full path of the File.

To keep it asynchronous, I have done:

Answer 1

import akka.pattern.pipe

Does the trick. Doing:

val reply = sender
future {
  val ans = searchAndCache(s)
  println("Input Request: "+s+" output:"+ans+" "+reply.path)
  ans
} pipeTo reply

replies back to the sender
