public ExtendedActorSystem()

Method Detail

provider

public abstract ActorRefProvider provider()

The ActorRefProvider is the only entity which creates all actor references within this actor system.

Specified by:

provider in interface ActorRefFactory

Specified by:

provider in class ActorSystem

Returns:

(undocumented)

guardian

public abstract InternalActorRef guardian()

The top-level supervisor of all actors created using system.actorOf(...).

Specified by:

guardian in interface ActorRefFactory

Specified by:

guardian in class ActorSystem

Returns:

(undocumented)

systemGuardian

public abstract InternalActorRef systemGuardian()

The top-level supervisor of all system-internal services like logging.

Returns:

(undocumented)

systemActorOf

public abstract ActorRef systemActorOf(Props props,
                                       java.lang.String name)

Create an actor in the "/system" namespace. This actor will be shut down during system.terminate only after all user actors have terminated.

Parameters:

props - (undocumented)

name - (undocumented)

Returns:

(undocumented)

threadFactory

public abstract java.util.concurrent.ThreadFactory threadFactory()

A ThreadFactory that can be used if the transport needs to create any Threads

Returns:

(undocumented)

dynamicAccess

public abstract DynamicAccess dynamicAccess()

ClassLoader wrapper which is used for reflective accesses internally. This is set to use the context class loader, if one is set, or the class loader which loaded the ActorSystem implementation. The context class loader is also set on all threads created by the ActorSystem, if one was set during creation.

Returns:

(undocumented)

logFilter

public abstract LoggingFilter logFilter()

Filter of log events that is used by the LoggingAdapter before publishing log events to the eventStream

Returns:

(undocumented)

printTree

public abstract java.lang.String printTree()

For debugging: traverse actor hierarchy and make string representation. Careful, this may OOM on large actor systems, and it is only meant for helping debugging in case something already went terminally wrong.

Returns:

(undocumented)
