Method Detail

nrOfInstances

int nrOfInstances(ActorSystem sys)

Initial number of routee instances

usePoolDispatcher

boolean usePoolDispatcher()

Use a dedicated dispatcher for the routees of the pool. The dispatcher is defined in 'pool-dispatcher' configuration property in the deployment section of the router.

newRoutee

Routee newRoutee(Props routeeProps,
                 ActorContext context)

INTERNAL API

enrichWithPoolDispatcher

Props enrichWithPoolDispatcher(Props routeeProps,
                               ActorContext context)

INTERNAL API

resizer

scala.Option<Resizer> resizer()

Pool with dynamically resizable number of routees return the Resizer to use. The resizer is invoked once when the router is created, before any messages can 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.

supervisorStrategy

SupervisorStrategy supervisorStrategy()

SupervisorStrategy for the head actor, i.e. for supervising the routees of the pool.

props

Props props(Props routeeProps)

Props for a pool router based on the settings defined by this instance and the supplied Props for the routees created by the router.

stopRouterWhenAllRouteesRemoved

boolean stopRouterWhenAllRouteesRemoved()

Specified by:

stopRouterWhenAllRouteesRemoved in interface RouterConfig

createRouterActor

akka.routing.RouterActor createRouterActor()

INTERNAL API

Specified by:

createRouterActor in interface RouterConfig
