| 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 PCDataimplementation 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 DataCacheimplementation that provides various
 statistics, logging, and timeout functionality common across cache
 implementations. | 
| AbstractQueryCache | Abstract QueryCacheimplementation that provides various
 statistics, logging, and timeout functionality common across cache
 implementations. | 
| ConcurrentDataCache | A DataCacheimplementation that is optimized for concurrent
 access. | 
| ConcurrentQueryCache | A QueryCacheimplementation that is optimized for concurrent
 access. | 
| DataCacheManagerImpl | Default data cache manager. | 
| DataCachePCDataGenerator | A PCDataGeneratorinstance which generates properly
 synchronized instances suitable for use in the cache. | 
| DataCachePCDataImpl | Specialized PCDataimplementation 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 StoreQueryimplementation 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. |
