Examples of org.hibernate.cache.CollectionRegion

org.hibernate.cache.CollectionRegion
Defines the contract for a cache region which will specifically be used to store collection data.
Impl note: Hibernate always deals with changes to collections which (potentially) has its data in the L2 cache by removing that collection data; in other words it never tries to update the cached state, thereby allowing it to avoid a bunch of concurrency problems. @author Steve Ebersole
