| CacheIdentityMap.java | Class | Purpose: A fixed size LRU cache
Using a linked list as well as the hashtable from the superclass a LRU cache is maintained. |
| CacheKey.java | Class | Purpose: Container class for storing objects in an IdentityMap. |
| FullIdentityMap.java | Class | Purpose: A FullIdentityMap holds all objects stored within it for the life of the application
Responsibilities:
- Guarantees identity
- Holds all cached objects indefinetly.
|
| HardCacheWeakIdentityMap.java | Class | Purpose: A weak cache is identical to the weak identity map, however the weak
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.java | Class | Purpose: Caches objects, and allows their retrieval by their primary key. |
| IdentityMapEnumeration.java | Class | Used to allow iterating over a map. |
| IdentityMapKeyEnumeration.java | Class | Used to allow iterating over a maps cache keys. |
| IdentityMapManager.java | Class | Purpose: Maintain identity maps for domain classes mapped with TopLink. |
| LinkedCacheKey.java | Class | Purpose: Provides the capability to insert CacheKeys into a Linked List. |
| NoIdentityMap.java | Class | Purpose: Provide the capability to not cache objects at all. |
| SoftCacheWeakIdentityMap.java | Class | Purpose: A weak cache is identical to the weak identity map, however the weak
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). |
| WeakCacheKey.java | Class | Purpose: Container class for storing objects in an IdentityMap. |
| WeakIdentityMap.java | Class | Purpose: A WeakIdentityMap holds all objects referenced by the application only. |
