  • Class
    Description
    Purpose: Caches objects, and allows their retrieval by their primary key.
    Abstract Enumeration interface implementation for IdentityMap interface.
    Defines a wrapper for a primary key (Id) to use as a key in the cache.
    Purpose: A fixed size LRU cache
    Purpose: Container class for storing objects in an IdentityMap.
    Purpose: A FullIdentityMap holds all objects stored within it for the life of the application.
    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).
    Purpose: Provides the interface for IdentityMap interaction.
    Allows to iterate over Object instances stored in CacheKey instances in the IdentityMap.
    Allows to iterate over CacheKey instances stored in the IdentityMap.
    Purpose: Maintain identity maps for domain classes mapped with EclipseLink.
    Purpose: Provides the capability to insert CacheKeys into a Linked List.
    Purpose: Provide the capability to not cache objects at all.
     
    Purpose: Container class for storing objects in an IdentityMap.
    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).
    Purpose: A SoftIdentityMap holds all objects referenced by the application.
    Unit of work specific identity map which avoid additional overhead not required in unit of work, such as locking and synchronization.
    Purpose: Container class for storing objects in an IdentityMap.
    Purpose: A WeakIdentityMap holds all objects referenced by the application only.
