is called the routees should also be registered,
typically by using createRoutees

to register routees,

Routers with dynamically resizable number of routees return the akka.routing.Resizer to use.

Overridable merge strategy, by default completely prefers “this” (i.e. no merge).
This trait represents a router factory: it produces the actual router actor and creates the routing table (a function which determines the recipients for each message which is to be dispatched). The resulting RoutedActorRef optimizes the sending of the message so that it does NOT go through the router’s mailbox unless the route returns an empty recipient set.
Caution: This means that the route function is evaluated concurrently without protection by the RoutedActorRef: either provide a reentrant (i.e. pure) implementation or do the locking yourself!
Caution: Please note that the akka.routing.Router which needs to be returned by
createActor()
should not send a message to itself in its constructor orpreStart()
or publish its self reference from there: if someone tries sending a message to that reference before the constructor of RoutedActorRef has returned, there will be aNullPointerException
