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()
