Constructor Detail

HazelcastClusterManager

public HazelcastClusterManager()

Constructor - gets config from classpath

HazelcastClusterManager

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

Constructor - config supplied

Parameters:

conf - Hazelcast config, not null

HazelcastClusterManager

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

Method Detail

setVertx

public void setVertx(io.vertx.core.Vertx vertx)

Specified by:

setVertx in interface io.vertx.core.spi.cluster.ClusterManager

join

public void join(io.vertx.core.Handler<io.vertx.core.AsyncResult<Void>> resultHandler)

Specified by:

join in interface io.vertx.core.spi.cluster.ClusterManager

getAsyncMultiMap

public <K,V> void getAsyncMultiMap(String name,
                                   io.vertx.core.Handler<io.vertx.core.AsyncResult<io.vertx.core.spi.cluster.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 io.vertx.core.spi.cluster.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 io.vertx.core.spi.cluster.ClusterManager

getNodes

public List<String> getNodes()

Specified by:

getNodes in interface io.vertx.core.spi.cluster.ClusterManager

nodeListener

public void nodeListener(io.vertx.core.spi.cluster.NodeListener listener)

Specified by:

nodeListener in interface io.vertx.core.spi.cluster.ClusterManager

getAsyncMap

public <K,V> void getAsyncMap(String name,
                              io.vertx.core.Handler<io.vertx.core.AsyncResult<io.vertx.core.shareddata.AsyncMap<K,V>>> resultHandler)

Specified by:

getAsyncMap in interface io.vertx.core.spi.cluster.ClusterManager

getSyncMap

public <K,V> Map<K,V> getSyncMap(String name)

Specified by:

getSyncMap in interface io.vertx.core.spi.cluster.ClusterManager

getLockWithTimeout

public void getLockWithTimeout(String name,
                               long timeout,
                               io.vertx.core.Handler<io.vertx.core.AsyncResult<io.vertx.core.shareddata.Lock>> resultHandler)

Specified by:

getLockWithTimeout in interface io.vertx.core.spi.cluster.ClusterManager

public void getCounter(String name,
                       io.vertx.core.Handler<io.vertx.core.AsyncResult<io.vertx.core.shareddata.Counter>> resultHandler)

memberRemoved

public void memberRemoved(com.hazelcast.core.MembershipEvent membershipEvent)

Specified by:

stateChanged

public void stateChanged(com.hazelcast.core.LifecycleEvent lifecycleEvent)

Specified by:

stateChanged in interface com.hazelcast.core.LifecycleListener

isActive

public boolean isActive()

Specified by:

isActive in interface io.vertx.core.spi.cluster.ClusterManager

memberAttributeChanged

public void memberAttributeChanged(com.hazelcast.core.MemberAttributeEvent memberAttributeEvent)

Specified by:

memberAttributeChanged in interface com.hazelcast.core.MembershipListener

getConfig

public com.hazelcast.config.Config getConfig()

Get the Hazelcast config.

Returns:

a config object

setConfig

public void setConfig(com.hazelcast.config.Config config)

Set the Hazelcast config.

Parameters:

config - a config object

loadConfig

public com.hazelcast.config.Config loadConfig()

Load Hazelcast config XML and transform it into a Config object. The content is read from:

1. the location denoted by the vertx.hazelcast.config sysprop, if present, or
2. the cluster.xml file on the classpath, if present, or
3. the default config file

The cluster manager uses this method to load the config when the node joins the cluster, if no config was provided upon creation.

You may use this method to get a base config and customize it before the node joins the cluster. In this case, don't forget to invoke setConfig(Config) after you applied your changes.

Returns:

a config object

getHazelcastInstance

public com.hazelcast.core.HazelcastInstance getHazelcastInstance()
