Cluster Methods

	Name	Description
	Down	Sends a command to DOWN the node specified by address. When a member is considered by the failure detector to be unreachable the leader is not allowed to perform its duties, such as changing status of new joining members to Up. The status of the unreachable member must be changed to Down, which can be done with this method.
	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.)
	Get	Retrieves the extension from the specified actor system.
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Join	Try to join this cluster node specified by address. A Join(Address) command is sent to the node to join. An actor system can only join a cluster once. Additional attempts will be ignored. When it has successfully joined it must be restarted to be able to join another cluster or to join the same cluster again.
	JoinSeedNodes	Joins the specified seed nodes without defining them in config. Especially useful from tests when Addresses are unknown before startup time. An actor system can only join a cluster once. Additional attempts will be ignored. When it has successfully joined it must be restarted to be able to join another cluster or to join the same cluster again.
	Leave	Sends a command to issue state transition to LEAVING for the node specified by address. The member will go through the status changes Leaving (not published to subscribers) followed by Exiting and finally Removed. Note that this command can be issued to any member in the cluster, not necessarily the one that is leaving. The cluster extension, but not the actor system, of the leaving member will be shutdown after the leader has changed status of the member to Exiting. Thereafter the member will be removed from the cluster. Normally this is handled automatically, but in case of network failures during this process it might still be necessary to set the node's status to Down in order to complete the removal.
	LeaveAsync	Causes the CURRENT node, i.e. the one calling this function, to leave the cluster. Once the returned Task completes, it means that the member has successfully been removed from the cluster.
	LeaveAsync(CancellationToken)	Causes the CURRENT node, i.e. the one calling this function, to leave the cluster. Once the returned Task completes in completed or cancelled state, it means that the member has successfully been removed from the cluster or cancellation token cancelled the task.
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	RegisterOnMemberRemoved	Registers the supplied callback to run once when the current cluster member is Removed. Typically used in combination with Leave(Address) and Terminate.
	RegisterOnMemberUp	Registers the supplied callback to run once when the current cluster member is Up. Typically used together with configuration option 'akka.cluster.min-nr-of-members' to defer some action, such as starting actors, until the cluster has reached a certain size.
	RemotePathOf	Generates the remote actor path by replacing the Address in the RootActorPath for the given ActorRef with the cluster's SelfAddress, unless address' host is already defined
	SendCurrentClusterState	Sends the current (full) state of the cluster to the specified actor. If you want this to happen periodically, you can use the Scheduler to schedule a call to this method. You can also call State directly for this information.
	Subscribe(IActorRef, Type)	Subscribe to one or more cluster domain events.
	Subscribe(IActorRef, ClusterEventSubscriptionInitialStateMode, Type)	Subscribe to one or more cluster domain events.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Unsubscribe(IActorRef)	Stops the specific actor from receiving all types of cluster domain events.
	Unsubscribe(IActorRef, Type)	Stops the specific actor from receiving a specific type of cluster domain event.
