Package containing all of the objects for Expresso's Cache Manager, a general-purpose
system for in-memory caching.
The caching system has many features such as built in Memory limitation, named

Any class that wishes to be stored in the Expresso system cache must implement
the Cacheable interface. |
| CacheCleaner.java | Class | This thread is initialized by CacheManager and slowly iterates through the
Caches clearing out expired items. |

| CacheEntry.java | Class | Wrapper for any Cacheable object to be stored in a cache.
This wrapper provides some utility services
to the cacheable object, like maintaining it's usage count
(for the least-frequently-used algorithm
used to free up cache space when needed) and the expiry time
of the object (for caches that use
timed expiry of objects - e.g. |

Cache Manager is a general-purpose class to handle all different
kinds of caches - it provides both "ordered" caches (stored as a
Vector of objects) and "unordered" caches (stored as a Hashtable).
The amount of data cached can be expressed as a count of items in
the specified list (e.g. |
| CacheStressTest.java | Class | Cache Stress test. |
| CacheSyncInterface.java | Interface | This represents the cache syncing interface for sending out notifications
to other servers to remove an object from their cache.
Not all classes have to implement everything... |
| CacheSyncMessage.java | Class | Data Bean for sending CacheSync messages across the wire. |
| CacheSystem.java | Interface | This is an interface for an underlying cache system. |
| CacheTest.java | Class | A test case to verify the functions of the Expresso CacheManager and related
objects. |
| CacheTestThread.java | Class | |
| DefaultCacheManager.java | Class | [Currently a placeholder. |
| OrderedCache.java | Class | Insert the type's description here. |
| UnOrderedCache.java | Class | Unordered cache is a hash map backed class. |
