  Commonly Used Patterns With Akka

  This package is used as a collection point for usage patterns which involve actors, futures, etc. but are loosely enough coupled to (multiple of) them to present them separately from the core implementation. Currently supported are:

  • ask: create a temporary one-off actor for receiving a reply to a message and complete a scala.concurrent.Future with it; returns said Future.
  • pipeTo: feed eventually computed value of a future to an akka.actor.ActorRef as a message.
  • pipeToSelection: feed eventually computed value of a future to an akka.actor.ActorSelection as a message.

  In Scala the recommended usage is to import the pattern from the package object:

  import akka.pattern.ask
  
  ask(actor, message) // use it directly
  actor ask message   // use it by implicit conversion

  For Java the patterns are available as static methods of the akka.pattern.Patterns class:

  import static akka.pattern.Patterns.ask;
  
  ask(actor, message);
