Hi Olger,
Akka Extensions are a mechanism that allows arbitrary actors to access a
given object or piece of functionality that is scoped to the ActorSystem,
i.e. created only once. This means that creation happens conceptually
“before the first actor is started”, it is merely retrieved when needed
(and optimized to be only created at the first appearance of need). This in
turn means that arguments to its constructor must come from the ActorSystem
itself, hence from configuration as you also figured out. You can use
system.dynamicAccess in order to reflectively create your factory from a
fully qualified class name.
Regards,
Roland
