Interface Summary

CacheDataDescription	Describes attributes regarding the type of data to be cached.
CollectionRegion	Defines the contract for a cache region which will specifically be used to store collection data.
EntityRegion	Defines the contract for a cache region which will specifically be used to store entity data.
GeneralDataRegion	Contract for general-purpose cache regions.
NaturalIdRegion	Defines the contract for a cache region which will specifically be used to store naturalId data.
OptimisticCacheSource	Contract for sources of optimistically lockable data sent to the second level cache.
QueryCache	Defines the contract for caches capable of storing query results.
QueryCacheFactory	Defines a factory for query cache instances.
QueryResultsRegion	Defines the contract for a cache region which will specifically be used to store query results.
Region	Defines a contract for accessing a particular named region within the underlying cache implementation.
RegionFactory	Contract for building second level cache regions.
TimestampsRegion	Defines the contract for a cache region which will specifically be used to store entity "update timestamps".
TransactionalDataRegion	Defines contract for regions which hold transactionally-managed data.
TransactionAwareCache	Marker interface for identifying Cache implementations which are aware of JTA transactions

Class Summary

CacheKey	Allows multiple entity classes / collection roles to be stored in the same cache region.
FilterKey	Allows cached queries to be keyed by enabled filters.
NaturalIdCacheKey	Defines a key for caching natural identifier resolutions into the second level cache.
QueryKey	A key that identifies a particular query with bound parameter values.
UpdateTimestampsCache	Tracks the timestamps of the most recent updates to particular tables.

Package org.hibernate.cache.spi Description

Defines the Hibernate second level caching SPI.

The initial contract here is RegionFactory whose implementations are responsible for configuring and managing lifecycle operations in regards to the particular underlying caching library. Its other main purpose is to build specializations Region instances based on the type of data we will be storing in that given region.
