   Send 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.

24.  def join(address: Address): Unit

    Try to join this cluster node with the node specified by 'address'.

    Try to join this cluster node with the node specified by 'address'. A 'Join(selfAddress)' 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.

    The name of the akka.actor.ActorSystem must be the same for all members of a cluster.

27.  def leave(address: Address): Unit

    Send command to issue state transition to LEAVING for the node specified by 'address'.

    Send command to issue state transition to LEAVING for the node specified by 'address'. The member will go through the status changes MemberStatus Leaving (not published to subscribers) followed by MemberStatus Exiting and finally MemberStatus 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 or JVM, 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.

    Java API: The supplied thunk will be run, once, when current cluster member is Removed.

    Java API: The supplied thunk will be run, once, when current cluster member is Removed. If the cluster has already been shutdown the thunk will run on the caller thread immediately. Typically used together cluster.leave(cluster.selfAddress) and then system.terminate().

    Java API: The supplied callback will be run, once, when current cluster member is Up.

    Java API: The supplied callback will be run, once, when 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.

34.  def registerOnMemberUp[T](code: ⇒ T): Unit

35.  def remotePathOf(actorRef: ActorRef): ActorPath

    Generate the remote actor path by replacing the Address in the RootActor Path for the given ActorRef with the cluster's selfAddress, unless address' host is already defined

36.  def selfAddress: Address

    The address of this cluster member.

37.  def selfRoles: Set[String]

38.  val selfUniqueAddress: UniqueAddress

    The address including a uid of this cluster member. The uid is needed to be able to distinguish different incarnations of a member with same hostname and port.

39.  def sendCurrentClusterState(receiver: ActorRef): Unit

    Send current (full) state of the cluster to the specified receiver.

    Send current (full) state of the cluster to the specified receiver. If you want this to happen periodically you need to schedule a call to this method yourself. Note that you can also retrieve the current state with #state.

40.  val settings: ClusterSettings
41.  def state: CurrentClusterState

    Current snapshot state of the cluster.

42.  def subscribe(subscriber: ActorRef, initialStateMode: SubscriptionInitialStateMode, to: Class[_]*): Unit

    Subscribe to one or more cluster domain events.

    Subscribe to one or more cluster domain events. The to classes can be akka.cluster.ClusterEvent.ClusterDomainEvent or subclasses.

    If initialStateMode is ClusterEvent.InitialStateAsEvents the events corresponding to the current state will be sent to the subscriber to mimic what you would have seen if you were listening to the events when they occurred in the past.

    If initialStateMode is ClusterEvent.InitialStateAsSnapshot a snapshot of akka.cluster.ClusterEvent.CurrentClusterState will be sent to the subscriber as the first message.

    Note that for large clusters it is more efficient to use InitialStateAsSnapshot.
