LocalRegionCache

public LocalRegionCache(org.hibernate.cache.spi.RegionFactory regionFactory,
                        String name,
                        com.hazelcast.core.HazelcastInstance hazelcastInstance,
                        org.hibernate.cache.cfg.spi.DomainDataRegionConfig regionConfig)

Parameters:

regionFactory - the region factory

name - the name for this region cache, which is also used to retrieve configuration/topic

hazelcastInstance - the HazelcastInstance to which this region cache belongs, used to retrieve configuration and to lookup an ITopic to register a MessageListener with (optional)

regionConfig - the region configuration

LocalRegionCache

public LocalRegionCache(org.hibernate.cache.spi.RegionFactory regionFactory,
                        String name,
                        com.hazelcast.core.HazelcastInstance hazelcastInstance,
                        org.hibernate.cache.cfg.spi.DomainDataRegionConfig regionConfig,
                        boolean withTopic)

Parameters:

regionFactory - the region factory

name - the name for this region cache, which is also used to retrieve configuration/topic

hazelcastInstance - the HazelcastInstance to which this region cache belongs, used to retrieve configuration and to lookup an ITopic to register a MessageListener with if withTopic is true (optional)

regionConfig - the region configuration

withTopic - true to register a MessageListener with the ITopic whose name matches this region cache if a HazelcastInstance was provided to look up the topic; otherwise, false not to register a listener even if an instance was provided
