Class	Description
AbstractIdentityMap	Purpose: Caches objects, and allows their retrieval by their primary key.
AbstractIdentityMapEnumeration<T>	Abstract Enumeration interface implementation for IdentityMap interface.
CacheId	Defines a wrapper for a primary key (Id) to use as a key in the cache.
CacheIdentityMap	Purpose: A fixed size LRU cache
CacheKey	Purpose: Container class for storing objects in an IdentityMap.
FullIdentityMap	Purpose: A FullIdentityMap holds all objects stored within it for the life of the application.
HardCacheWeakIdentityMap	Purpose: A HardCacheWeakIdentityMap is identical to the weak identity map, however the weak reference can be a performance problem for some types of apps because it can cause too much garbage collection of objects read causing them to be re-read and re-built (this defeats the purpose of the cache).
IdentityMap	Purpose: Provides the interface for IdentityMap interaction.
IdentityMapEnumeration	Allows to iterate over Object instances stored in CacheKey instances in the IdentityMap.
IdentityMapKeyEnumeration	Allows to iterate over CacheKey instances stored in the IdentityMap.
IdentityMapManager	Purpose: Maintain identity maps for domain classes mapped with EclipseLink.
LinkedCacheKey	Purpose: Provides the capability to insert CacheKeys into a Linked List.
NoIdentityMap	Purpose: Provide the capability to not cache objects at all.
QueueableWeakCacheKey
SoftCacheKey	Purpose: Container class for storing objects in an IdentityMap.
SoftCacheWeakIdentityMap	Purpose: A SoftCacheWeakIdentityMap is identical to the WeakIdentityMap, however the weak reference can be a performance problem for some types of apps because it can cause too much garbage collection of objects read causing them to be re-read and re-built (this defeats the purpose of the cache).
SoftIdentityMap	Purpose: A SoftIdentityMap holds all objects referenced by the application.
UnitOfWorkIdentityMap	Unit of work specific identity map which avoid additional overhead not required in unit of work, such as locking and synchronization.
WeakCacheKey	Purpose: Container class for storing objects in an IdentityMap.
WeakIdentityMap	Purpose: A WeakIdentityMap holds all objects referenced by the application only.
