public class SmallestMailboxRouter extends java.lang.Object implements DeprecatedRouterConfig, scala.Product, scala.Serializable
Please note that providing both 'nrOfInstances' and 'routees' does not make logical sense as this means
that the router should both create new actors and use the 'routees' actor(s).
In this case the 'nrOfInstances' will be ignored and the 'routees' will be used.
The configuration parameter trumps the constructor arguments. This means that
if you provide either 'nrOfInstances' or 'routees' during instantiation they will
be ignored if the router is defined in the configuration file for the actor being used.
Any routees that are created by a router will be created as the router's children. The router is therefore also the children's supervisor.
The supervision strategy of the router actor can be configured with
withSupervisorStrategy(akka.actor.SupervisorStrategy)
. If no strategy is provided, routers default to
a strategy of “always escalate”. This means that errors are passed up to the
router's supervisor for handling.
The router's supervisor will treat the error as an error with the router itself. Therefore a directive to stop or restart will cause the router itself to stop or restart. The router, in turn, will cause its children to stop and restart.

be sent to it. Resize is also triggered when messages are sent to the routees, and the
resizer is invoked asynchronously, i.e. not necessarily before the message has been sent.public java.lang.String routerDispatcher()
