The basic ActorSystem covers all that is needed for locally running actors, using futures and so on. In addition, more features can hook into it and thus become visible to actors et al by registering themselves as extensions. This is accomplished by providing an extension—which is an object implementing this trait—to
ActorSystem.registerExtension(...)or by specifying the corresponding option in the configuration passed to ActorSystem, which will then instantiate (without arguments) each FQCN and register the result.The extension itself can be created in any way desired and has full access to the ActorSystem implementation.
This trait is only a marker interface to signify an Akka Extension, see ExtensionKey for a concise way of formulating extensions.
