public BrokerTopologyManagerImpl(Supplier<Set<Member>> membersSupplier)

Method Details

getTopology

public BrokerClusterState getTopology()

Specified by:

getTopology in interface BrokerTopologyManager

Returns:

the current known cluster state or null if the topology was not fetched yet

setTopology

public void setTopology(BrokerClusterStateImpl topology)

addTopologyListener

public void addTopologyListener(BrokerTopologyListener listener)

Description copied from interface: BrokerTopologyManager

Adds the topology listener. For each existing brokers, the listener will be notified via BrokerTopologyListener.brokerAdded(MemberId). After that, the listener gets notified of every new broker added or removed events.

Specified by:

addTopologyListener in interface BrokerTopologyManager

Parameters:

listener - the topology listener

removeTopologyListener

public void removeTopologyListener(BrokerTopologyListener listener)

Description copied from interface: BrokerTopologyManager

Removes the given topology listener by identity.

Specified by:

removeTopologyListener in interface BrokerTopologyManager

Parameters:

listener - the listener to remove

start

public ActorFuture<Void> start(ActorSchedulingService actorScheduler)

getName

public String getName()

Overrides:

getName in class Actor

onActorStarted

protected void onActorStarted()

Overrides:

onActorStarted in class Actor

event

public void event(ClusterMembershipEvent event)

Specified by:

event in interface EventListener<ClusterMembershipEvent>

onClusterTopologyChanged

public void onClusterTopologyChanged(ClusterTopology clusterTopology)

Specified by:

onClusterTopologyChanged in interface GatewayClusterTopologyService.Listener
