java.lang.Object

com.atlassian.confluence.impl.cache.hazelcast.hibernate.HazelcastIMapRegionFactoryWrapper

All Implemented Interfaces:

Serializable, org.hibernate.cache.spi.RegionFactory, org.hibernate.service.Service

public final class HazelcastIMapRegionFactoryWrapper
extends Object
implements org.hibernate.cache.spi.RegionFactory

An implementation of Hibernate's RegionFactory which delegates through to a HazelcastCacheRegionFactory instance, and ensures that any IMaps used by that indtance are pre-created with our desired configuration in advance.

initHazelcastMap

protected String initHazelcastMap(String regionName)

Because both HazelcastCacheRegionFactory talks directly to the Hazelcast API to get its config, we need to pre-configure Hazelcast with our desired config first. We use atlassian-cache-hazelcast to do that. Since atlassian-cache-hazelcast prefixes the names of its Hazelcast data structures, we need to reproduce that prefixing here, so that the delegate region factory picks up the correct structure.

This is pretty ghaslty, obviously.

Parameters:

regionName - The name of the hibernate region

Returns:

The modified region nme that we pass to the delegate region factory.
