Description

Interface Summary

Cache	Implementors define a caching algorithm.
CacheConcurrencyStrategy	Implementors manage transactional access to cached data.
CacheConcurrencyStrategy.SoftLock	Marker interface, denoting a client-visible "soft lock" on a cached item.
CacheProvider	Support for pluggable caches.
OptimisticCache	A contract for transactional cache implementations which support optimistic locking of items within the cache.
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.
ReadWriteCache.Lockable

Class Summary

AbstractJndiBoundCacheProvider	Support for CacheProvider implementations which are backed by caches bound into JNDI namespace.
CacheFactory
CacheKey	Allows multiple entity classes / collection roles to be stored in the same cache region.
EhCache	EHCache plugin for Hibernate EHCache uses a MemoryStore and a DiskStore.
EhCacheProvider	Cache Provider plugin for ehcache-1.2.
FilterKey	Allows cached queries to be keyed by enabled filters.
HashtableCache	A lightweight implementation of the Cache interface
HashtableCacheProvider	A simple in-memory Hashtable-based cache impl.
JndiBoundTreeCacheProvider	Support for JBossCache (TreeCache), where the cache instance is available via JNDI lookup.
NoCacheProvider	Implementation of NoCacheProvider.
NonstrictReadWriteCache	Caches data that is sometimes updated without ever locking the cache.
OptimisticTreeCache	Represents a particular region within the given JBossCache TreeCache utilizing TreeCache's optimistic locking capabilities.
OptimisticTreeCache.CircumventChecksDataVersion	Used to signal to a DataVersionAdapter to simply not perform any checks.
OptimisticTreeCache.DataVersionAdapter
OptimisticTreeCache.NonLockingDataVersion	Used in regions where no locking should ever occur.
OptimisticTreeCacheProvider	Support for a standalone JBossCache TreeCache instance utilizing TreeCache's optimistic locking capabilities.
OSCache
OSCacheProvider	Support for OpenSymphony OSCache.
QueryKey	A key that identifies a particular query with bound parameter values
ReadOnlyCache	Caches data that is never updated.
ReadWriteCache	Caches data that is sometimes updated while maintaining the semantics of "read committed" isolation level.
ReadWriteCache.Item	An item of cached data, timestamped with the time it was cached,.
ReadWriteCache.Lock	A soft lock which supports concurrent locking, timestamped with the time it was released
StandardQueryCache	The standard implementation of the Hibernate QueryCache interface.
StandardQueryCacheFactory	Standard Hibernate implementation of the QueryCacheFactory interface.
SwarmCache
SwarmCacheProvider	Support for SwarmCache replicated cache.
Timestamper	Generates increasing identifiers (in a single VM only).
TransactionalCache	Support for fully transactional cache implementations like JBoss TreeCache.
TreeCache	Represents a particular region within the given JBossCache TreeCache.
TreeCacheProvider	Support for a standalone JBossCache (TreeCache) instance.
UpdateTimestampsCache	Tracks the timestamps of the most recent updates to particular tables.

Exception Summary

CacheException	Something went wrong in the cache
NoCachingEnabledException	Implementation of NoCachingEnabledException.

Package org.hibernate.cache Description

This package defines APIs and implementations for the second-level cache and query cache.

Cache abstracts the underlying cache implementation. CacheConcurrencyStrategy abstracts various strategies for maintaining consistency between the cache and database. QueryCache abstracts the query result set cache.
