RoundRobinRouter

public RoundRobinRouter(int nr)

Java API: Constructor that sets nrOfInstances to be created.

Parameters:

nr - (undocumented)

RoundRobinRouter

public RoundRobinRouter(java.lang.Iterable<java.lang.String> routeePaths)

Java API: Constructor that sets the routees to be used.

Parameters:

routeePaths - string representation of the actor paths of the routees that will be looked up using actorFor in ActorRefProvider

RoundRobinRouter

public RoundRobinRouter(Resizer resizer)

Java API: Constructor that sets the resizer to be used.

Parameters:

resizer - (undocumented)

Method Detail

apply

public static RoundRobinRouter apply(scala.collection.immutable.Iterable<ActorRef> routees)

Creates a new RoundRobinRouter, routing to the specified routees

Parameters:

routees - (undocumented)

Returns:

(undocumented)

create

public static RoundRobinRouter create(java.lang.Iterable<ActorRef> routees)

nrOfInstances

public int nrOfInstances()

Description copied from interface: Pool

Initial number of routee instances

Specified by:

nrOfInstances in interface Pool

Returns:

(undocumented)

routees

public scala.collection.immutable.Iterable<java.lang.String> routees()

resizer

public scala.Option<Resizer> resizer()

Description copied from interface: Pool

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.

Specified by:

resizer in interface Pool

Returns:

(undocumented)

routerDispatcher

public java.lang.String routerDispatcher()

Description copied from interface: RouterConfig

Dispatcher ID to use for running the &ldquo;head&rdquo; actor, which handles supervision, death watch and router management messages

Specified by:

routerDispatcher in interface RouterConfig

Returns:

(undocumented)

supervisorStrategy

public SupervisorStrategy supervisorStrategy()

Description copied from interface: Pool

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

Specified by:

supervisorStrategy in interface Pool

Returns:

(undocumented)

paths

public scala.collection.immutable.Iterable<java.lang.String> paths()

Specified by:

paths in interface Group

withDispatcher

public RoundRobinRouter withDispatcher(java.lang.String dispatcherId)

Java API for setting routerDispatcher

Parameters:

dispatcherId - (undocumented)

Returns:

(undocumented)

withSupervisorStrategy

public RoundRobinRouter withSupervisorStrategy(SupervisorStrategy strategy)

Java API for setting the supervisor strategy to be used for the &ldquo;head&rdquo; Router actor.

Specified by:

withSupervisorStrategy in interface PoolOverrideUnsetConfig<RoundRobinRouter>

Parameters:

strategy - (undocumented)

Returns:

(undocumented)

withResizer

public RoundRobinRouter withResizer(Resizer resizer)

Java API for setting the resizer to be used.

Specified by:

withResizer in interface PoolOverrideUnsetConfig<RoundRobinRouter>

Parameters:

resizer - (undocumented)

Returns:

(undocumented)

withFallback

public RouterConfig withFallback(RouterConfig other)

Uses the resizer and/or the supervisor strategy 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.

Specified by:

withFallback in interface RouterConfig

Parameters:

other - (undocumented)

Returns:

(undocumented)

createRouter

public Router createRouter(ActorSystem system)

Description copied from interface: RouterConfig

Create the actual router, responsible for routing messages to routees.

Specified by:

createRouter in interface RouterConfig

Parameters:

system - the ActorSystem this router belongs to

Returns:

(undocumented)
