FromConfig

public FromConfig()

Method Detail

getInstance

public static FromConfig$ getInstance()

Java API: get the singleton instance

apply

public static final FromConfig apply(scala.Option<Resizer> resizer,
               SupervisorStrategy supervisorStrategy,
               java.lang.String routerDispatcher)

unapply

public static final scala.Option<java.lang.String> unapply(FromConfig fc)

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

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

routerDispatcher

public java.lang.String routerDispatcher()

Description copied from interface: RouterConfig

Dispatcher ID to use for running the “head” actor, which handles supervision, death watch and router management messages

Specified by:

routerDispatcher in interface RouterConfig

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

verifyConfig

public void verifyConfig(ActorPath path)

Description copied from interface: RouterConfig

Check that everything is there which is needed. Called in constructor of RoutedActorRef to fail early.

Specified by:

verifyConfig in interface RouterConfig

withSupervisorStrategy

public FromConfig withSupervisorStrategy(SupervisorStrategy strategy)

Setting the supervisor strategy to be used for the “head” Router actor.

withResizer

public FromConfig withResizer(Resizer resizer)

Setting the resizer to be used.

withDispatcher

public FromConfig withDispatcher(java.lang.String dispatcherId)

Setting the dispatcher to be used for the router head actor, which handles supervision, death watch and router management messages.

nrOfInstances

public int nrOfInstances()

Description copied from interface: Pool

Initial number of routee instances

Specified by:

nrOfInstances in interface Pool

props

public Props props()

Props for a group router based on the settings defined by this instance.
