Description

Interface Summary

DataCache	Interface that must be implemented by any level 2 cache used by OpenJPA.
DataCacheManager	Manages the system's data and query caches.
DataCachePCData	Specialized PCData implementation for data caching.
DataCachePCDataGenerator.Timed	Simple interface to give access to expiration time.
ExpirationListener	An entity that wishes to be notified when cache keys expire.
QueryCache	Interface that must be implemented by any level 2 query cache used by OpenJPA.
TypesChangedListener	An entity that wishes to be notified when types change.

Class Summary

AbstractDataCache	Abstract DataCache implementation that provides various statistics, logging, and timeout functionality common across cache implementations.
AbstractQueryCache	Abstract QueryCache implementation that provides various statistics, logging, and timeout functionality common across cache implementations.
Caches
ConcurrentDataCache	A DataCache implementation that is optimized for concurrent access.
ConcurrentQueryCache	A QueryCache implementation that is optimized for concurrent access.
DataCacheManagerImpl	Default data cache manager.
DataCachePCDataGenerator	A PCDataGenerator instance which generates properly synchronized instances suitable for use in the cache.
DataCachePCDataImpl	Specialized PCData implementation for data caching.
DataCacheScheduler	Cron-style cache eviction.
DataCacheStoreManager	StoreManager proxy that delegates to a data cache when possible.
DelegatingDataCache	Delegating data cache that can also perform exception translation for use in facades.
DelegatingQueryCache	Delegating query cache that can also perform exception translation for use in facades.
ExpirationEvent	An event indicating the expiration of an object from the data cache, or an expiration of a result list from the query cache.
QueryCacheStoreQuery	A StoreQuery implementation that caches the OIDs involved in the query, and can determine whether or not the query has been dirtied.
QueryCacheStoreQuery.CachedList	Result list implementation for a cached query result.
QueryKey	This class stores information about a particular invocation of a query.
QueryResult	A query result.
TypesChangedEvent	An event indicating that instances of given persistent types have been modified.
