init

public void init(ActorSystemImpl _system)

Description copied from interface: ActorRefProvider

INTERNAL API: Initialization of an ActorRefProvider happens in two steps: first construction of the object with settings, eventStream, etc. and then—when the ActorSystem is constructed—the second phase during which actors may be created (e.g. the guardians).

Specified by:

init in interface ActorRefProvider

Parameters:

_system - (undocumented)

actorFor

public InternalActorRef actorFor(InternalActorRef ref,
                                 java.lang.String path)

Deprecated.

use actorSelection instead of actorFor. Since 2.2.

Description copied from interface: ActorRefProvider

INTERNAL API

Create actor reference for a specified local or remote path, which will be parsed using java.net.URI. If no such actor exists, it will be (equivalent to) a dead letter reference. If s is a relative URI, resolve it relative to the given ref.

Specified by:

actorFor in interface ActorRefProvider

Parameters:

ref - (undocumented)

path - (undocumented)

Returns:

(undocumented)

actorFor

public InternalActorRef actorFor(ActorPath path)

Deprecated.

use actorSelection instead of actorFor. Since 2.2.

Description copied from interface: ActorRefProvider

INTERNAL API

Create actor reference for a specified local or remote path. If no such actor exists, it will be (equivalent to) a dead letter reference.

Actor references acquired with actorFor do not always include the full information about the underlying actor identity and therefore such references do not always compare equal to references acquired with actorOf, sender, or context.self.

Specified by:

actorFor in interface ActorRefProvider

Parameters:

path - (undocumented)

Returns:

(undocumented)

actorFor

public InternalActorRef actorFor(InternalActorRef ref,
                                 scala.collection.Iterable<java.lang.String> path)

Deprecated.

use actorSelection instead of actorFor. Since 2.2.

Description copied from interface: ActorRefProvider

INTERNAL API

Create actor reference for the specified child path starting at the given starting point. This method always returns an actor which is “logically local”, i.e. it cannot be used to obtain a reference to an actor which is not physically or logically attached to this actor system.

Specified by:

actorFor in interface ActorRefProvider

Parameters:

ref - (undocumented)

path - (undocumented)

Returns:

(undocumented)

resolveActorRef

public ActorRef resolveActorRef(java.lang.String path)

Description copied from interface: ActorRefProvider

Create actor reference for a specified path. If no such actor exists, it will be (equivalent to) a dead letter reference.

Specified by:

resolveActorRef in interface ActorRefProvider

Parameters:

path - (undocumented)

Returns:

(undocumented)

resolveActorRef

public ActorRef resolveActorRef(ActorPath path)

Description copied from interface: ActorRefProvider

Create actor reference for a specified path. If no such actor exists, it will be (equivalent to) a dead letter reference.

Specified by:

resolveActorRef in interface ActorRefProvider

Parameters:

path - (undocumented)

Returns:

(undocumented)

resolveActorRef

public InternalActorRef resolveActorRef(InternalActorRef ref,
                                        scala.collection.Iterable<java.lang.String> pathElements)

INTERNAL API

Parameters:

ref - (undocumented)

pathElements - (undocumented)

Returns:

(undocumented)

actorOf

public InternalActorRef actorOf(ActorSystemImpl system,
                                Props props,
                                InternalActorRef supervisor,
                                ActorPath path,
                                boolean systemService,
                                scala.Option<Deploy> deploy,
                                boolean lookupDeploy,
                                boolean async)

Description copied from interface: ActorRefProvider

INTERNAL API: Actor factory with create-only semantics: will create an actor as described by props with the given supervisor and path (may be different in case of remote supervision). If systemService is true, deployment is bypassed (local-only). If Some(deploy) is passed in, it should be regarded as taking precedence over the nominally applicable settings, but it should be overridable from external configuration; the lookup of the latter can be suppressed by setting lookupDeploy to false.

Specified by:

actorOf in interface ActorRefProvider

Parameters:

system - (undocumented)

props - (undocumented)

supervisor - (undocumented)

path - (undocumented)

systemService - (undocumented)

deploy - (undocumented)

lookupDeploy - (undocumented)

async - (undocumented)

Returns:

(undocumented)

getExternalAddressFor

public scala.Option<Address> getExternalAddressFor(Address addr)

Description copied from interface: ActorRefProvider

Obtain the address which is to be used within sender references when sending to the given other address or none if the other address cannot be reached from this system (i.e. no means of communication known; no attempt is made to verify actual reachability).

Specified by:

getExternalAddressFor in interface ActorRefProvider

Parameters:

addr - (undocumented)

Returns:

(undocumented)

getDefaultAddress

public Address getDefaultAddress()

Description copied from interface: ActorRefProvider

Obtain the external address of the default transport.

Specified by:
