The RouteeProvider responsible for creating or
looking up routees.
The RouteeProvider responsible for creating or
looking up routees. It's used in createRoute to register routees,
and also from akka.routing.Resizer.
Returns true if the actor currently has any pending messages in the mailbox, i.
Returns true if the actor currently has any pending messages in the mailbox, i.e. the mailbox is not empty. It will always return false for remote actors. Method is exposed to subclasses to be able to implement custom routers based on mailbox and actor internal state.
Returns true if the actor is currently processing a message.
Returns true if the actor is currently processing a message. It will always return false for remote actors. Method is exposed to subclasses to be able to implement custom routers based on mailbox and actor internal state.
Returns true if the actor is currently suspended.
Returns true if the actor is currently suspended. It will always return false for remote actors. Method is exposed to subclasses to be able to implement custom routers based on mailbox and actor internal state.
Returns the number of pending messages in the mailbox of the actor.
Returns the number of pending messages in the mailbox of the actor. It will always return 0 for remote actors. Method is exposed to subclasses to be able to implement custom routers based on mailbox and actor internal state.

Uses the resizer of the given Routerconfig if this RouterConfig doesn't have one, i.e. the resizer defined in code is used if resizer was not defined in config.
Java API for setting the supervisor strategy to be used for the “head” Router actor.
A Router that tries to send to the non-suspended routee with fewest messages in mailbox. The selection is done in this order:
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. = Supervision Setup = The router creates a “head” actor which supervises and/or monitors the routees. Instances are created as children of this actor, hence the children are not supervised by the parent of the router. Common choices are to always escalate (meaning that fault handling is always applied to all children simultaneously; this is the default) or use the parent’s strategy, which will result in routed children being treated individually, but it is possible as well to use Routers to give different supervisor strategies to different groups of children. {{{ class MyActor extends Actor { override val supervisorStrategy = ... val poolAsAWhole = context.actorOf(Props[SomeActor].withRouter(SmallestMailboxRouter(5))) val poolIndividuals = context.actorOf(Props[SomeActor].withRouter( SmallestMailboxRouter(5, supervisorStrategy = this.supervisorStrategy))) val specialChild = context.actorOf(Props[SomeActor].withRouter( SmallestMailboxRouter(5, supervisorStrategy = OneForOneStrategy() { ... }))) } }}}
