tempPath in interface ActorRefProvider

theOneWhoWalksTheBubblesOfSpaceTime

public akka.actor.InternalActorRef theOneWhoWalksTheBubblesOfSpaceTime()

Top-level anchor for the supervision hierarchy of this actor system. Will receive only Supervise/ChildTerminated system messages or Failure message.

dispatcher

public MessageDispatcher dispatcher()

terminationPromise

public scala.concurrent.Promise<scala.runtime.BoxedUnit> terminationPromise()

terminationFuture

public scala.concurrent.Future<scala.runtime.BoxedUnit> terminationFuture()

registerExtraNames

public void registerExtraNames(scala.collection.immutable.Map<java.lang.String,akka.actor.InternalActorRef> _extras)

Higher-level providers (or extensions) might want to register new synthetic top-level paths for doing special stuff. This is the way to do just that. Just be careful to complete all this before ActorSystem.start() finishes, or before you start your own auto-spawned actors.

rootGuardianStrategy

protected SupervisorStrategy rootGuardianStrategy()

Overridable supervision strategy to be used by the “/user” guardian.

guardianStrategy

protected SupervisorStrategy guardianStrategy()

Overridable supervision strategy to be used by the “/user” guardian.

systemGuardianStrategy

protected SupervisorStrategy systemGuardianStrategy()

Overridable supervision strategy to be used by the “/user” guardian.

rootGuardian

public akka.actor.LocalActorRef rootGuardian()

Description copied from interface: ActorRefProvider

Reference to the supervisor of guardian and systemGuardian; this is exposed so that the ActorSystemImpl can use it as lookupRoot, i.e. for anchoring absolute actor look-ups.

Specified by:

rootGuardian in interface ActorRefProvider

guardian

                              ActorPath path)

Description copied from interface: ActorRefProvider

Description copied from interface: ActorRefProvider

Unregister a temporary actor from the “/temp” path (i.e. obtained from tempPath()); do NOT pass in any other path.

Specified by:

unregisterTempActor in interface ActorRefProvider

init

public void init(akka.actor.ActorSystemImpl _system)

Description copied from interface: ActorRefProvider

Initialization of an ActorRefProvider happens in two steps: first construction of the object with settings, eventStream, scheduler, 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

actorFor

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

Description copied from interface: ActorRefProvider

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

actorFor

public akka.actor.InternalActorRef actorFor(ActorPath path)

Description copied from interface: ActorRefProvider

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

Specified by:

actorFor in interface ActorRefProvider

actorFor

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

Description copied from interface: ActorRefProvider

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

actorOf

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

Description copied from interface: ActorRefProvider

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

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

getDefaultAddress

public Address getDefaultAddress()

Description copied from interface: ActorRefProvider

Obtain the external address of the default transport.

Specified by:

getDefaultAddress in interface ActorRefProvider
