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);

Type Members

final class Discovery extends Extension
final class Lookup extends NoSerializationVerificationNeeded
A service lookup.
A service lookup. It is up to each method to decide what to do with the optional portName and protocol fields. For example portName could be used to distinguish between Akka remoting ports and HTTP ports.
abstract class ServiceDiscovery extends AnyRef
Implement to provide a service discovery method

Value Members

object Discovery extends ExtensionId[Discovery] with ExtensionIdProvider
