Constructor Detail

HazelcastClusterManager

public HazelcastClusterManager()

Constructor - gets config from classpath

HazelcastClusterManager

public HazelcastClusterManager(com.hazelcast.config.Config conf)

Constructor - config supplied

Parameters:

conf -

HazelcastClusterManager

public HazelcastClusterManager(com.hazelcast.core.HazelcastInstance instance)

Method Detail

setVertx

public void setVertx(Vertx vertx)

Specified by:

setVertx in interface ClusterManager

join

public void join(Handler<AsyncResult<Void>> resultHandler)

Specified by:

join in interface ClusterManager

getAsyncMultiMap

public <K,V> void getAsyncMultiMap(String name,
                                   Handler<AsyncResult<AsyncMultiMap<K,V>>> resultHandler)

Every eventbus handler has an ID. SubsMap (subscriber map) is a MultiMap which maps handler-IDs with server-IDs and thus allows the eventbus to determine where to send messages.

Specified by:

getAsyncMultiMap in interface ClusterManager

Parameters:

name - A unique name by which the the MultiMap can be identified within the cluster. See the cluster config file (e.g. cluster.xml in case of HazelcastClusterManager) for additional MultiMap config parameters.

resultHandler - handler receiving the multimap

getNodeID

public String getNodeID()

Specified by:

getNodeID in interface ClusterManager

getNodes

public List<String> getNodes()

Specified by:

getNodes in interface ClusterManager

nodeListener

Specified by:
