org.vertx.java.core.eventbus.impl.hazelcast.HazelcastClusterManager

All Implemented Interfaces:

ClusterManager

public class HazelcastClusterManager
extends java.lang.Object
implements ClusterManager

A cluster manager based on a HazelcastInstance singleton.

Please be aware of the typical issues with singletons. E.g. all junit tests will share a single instance and the data (subsMap).

Method Detail

getConfig

protected com.hazelcast.config.Config getConfig(java.lang.String configfile)

Get the Hazelcast config

Parameters:

configfile - May be null in which case it gets the default (cluster.xml) will be used.

Returns:

a config object

getSubsMap

public SubsMap getSubsMap(java.lang.String name)

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:

getSubsMap 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.

Returns:

subscription map

close

public void close()

Because it implements a singleton, close() needs to be a noop

Specified by:

close in interface ClusterManager

getInstance

public com.hazelcast.core.HazelcastInstance getInstance()

Provide access to the singleton Hazelcast instance, e.g. to properly close it.

Returns:

hazelcast instance
