Interface CollectionRegion

All Superinterfaces:
Region, TransactionalDataRegion
All Known Implementing Classes:
CollectionRegionAdapter, CollectionRegionImpl, CollectionRegionImpl

public interface CollectionRegion
extends TransactionalDataRegion

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.
