Constructor Details

LocalRegionCache

protected LocalRegionCache(org.hibernate.cache.spi.RegionFactory regionFactory,
 String name,
 com.hazelcast.core.HazelcastInstance hazelcastInstance,
 org.hibernate.cache.cfg.spi.DomainDataRegionConfig regionConfig,
 boolean withTopic,
 LocalRegionCache.EvictionConfig evictionConfig,
 FreeHeapBasedCacheEvictor freeHeapBasedCacheEvictor)

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

evictionConfig - provides the parameters which should be used when evicting entries from the cache; if null, this will be derived from the Hazelcast MapConfig; if the MapConfig cannot be resolved, this will use defaults.

freeHeapBasedCacheEvictor - performs the free-heap-based eviction
