 | ClusterReceptionist Class |
ClusterClient connects to this actor to retrieve. The ClusterReceptionist is supposed to be started on all nodes, or all nodes with specified role, in the cluster. The receptionist can be started with the Get(ActorSystem) or as an ordinary actor (use the factory method Props(IActorRef, ClusterReceptionistSettings)).
The receptionist forwards messages from the client to the associated DistributedPubSubMediator, i.e. the client can send messages to any actor in the cluster that is registered in the DistributedPubSubMediator. Messages from the client are wrapped in Send, SendToAll or Publish with the semantics described in distributed publish/subscribe.
Response messages from the destination actor are tunneled via the receptionist to avoid inbound connections from other cluster nodes to the client, i.e. the Sender, as seen by the destination actor, is not the client itself. The Sender of the response messages, as seen by the client, is preserved as the original sender, so the client can choose to send subsequent messages directly to the actor in the cluster.

SyntaxThe ClusterReceptionist type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | ClusterReceptionist |
TBD
|
Properties| Name | Description | |
|---|---|---|
 | Self |
Gets the self ActorRef
(Inherited from ActorBase.) |
| Sender |
Gets the sending ActorRef of the current message
(Inherited from ActorBase.) |
Methods| Name | Description | |
|---|---|---|
| AroundPostRestart |
Can be overridden to intercept calls to `PostRestart`. Calls `PostRestart` by default.
(Inherited from ActorBase.) |
| AroundPostStop |
Can be overridden to intercept calls to `PostStop`. Calls `PostStop` by default..
(Inherited from ActorBase.) |
| AroundPreRestart |
Can be overridden to intercept calls to `PreRestart`. Calls `PreRestart` by default.
(Inherited from ActorBase.) |
| AroundPreStart |
Can be overridden to intercept calls to `PreStart`. Calls `PreStart` by default.
(Inherited from ActorBase.) |
 | AroundReceive |
TBD
(Inherited from ActorBase.) |
| Become |
Changes the actor's command behavior and replaces the current receive handler with the specified handler.
(Inherited from ActorBase.) |
| BecomeStacked |
Changes the actor's behavior and replaces the current receive handler with the specified handler.
The current handler is stored on a stack, and you can revert to it by calling UnbecomeStacked (Inherited from ActorBase.)RemarksPlease note, that in order to not leak memory, make sure every call to BecomeStacked(Receive)
is matched with a call to UnbecomeStacked. |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object.) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Serves as the default hash function. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| PostRestart |
User overridable callback: By default it calls `PreStart()`.
Is called right AFTER restart on the newly created Actor to allow reinitialization after an Actor crash.
(Inherited from ActorBase.) |
| PostStop |
TBD
(Overrides ActorBasePostStop.) |
| PreRestart |
User overridable callback: '''By default it disposes of all children and then calls `postStop()`.'''
Is called on a crashed Actor right BEFORE it is restarted to allow clean
up of resources before Actor is terminated.
(Inherited from ActorBase.) |
| PreStart |
TBD
(Overrides ActorBasePreStart.) |
 | Props |
Factory method for ClusterReceptionistProps.
|
| Receive |
TBD
(Overrides ActorBaseReceive(Object).) |
| SetReceiveTimeout | Defines the inactivity timeout after which the sending of a ReceiveTimeout message is triggered. When specified, the receive function should be able to handle a ReceiveTimeout message. Please note that the receive timeout might fire and enqueue the ReceiveTimeout message right after another message was enqueued; hence it is not guaranteed that upon reception of the receive timeout there must have been an idle period beforehand as configured via this method. Once set, the receive timeout stays in effect (i.e. continues firing repeatedly after inactivity periods). Pass in null to switch off this feature. |
| SupervisorStrategy |
TBD
(Inherited from ActorBase.) |
| ToString | Returns a string that represents the current object. (Inherited from Object.) |
| UnbecomeStacked |
Reverts the Actor behavior to the previous one on the behavior stack.
(Inherited from ActorBase.) |
| Unhandled |
Is called when a message isn't handled by the current behavior of the actor
by default it fails with either a DeathPactException (in
case of an unhandled Terminated message) or publishes an UnhandledMessage
to the actor's system's EventStream (Inherited from ActorBase.) |
