Classes:

• Cacheable: Any object that implements this interface can be cached using the services of the CacheManager/CacheFactory. In addition to implementing this interface the class must be public and it must have a public no-arg constructor. This is because the cache manager will construct objects itself and then set their identity by calling the setIdentity method. A Cacheable object has five states: No identity - The object is only accessable by the cache manager Identity, clean, unkept - The object has an identity, is clean but is only accessable by the cache manager Identity, clean, kept - The object has an identity, ...

• SizedCacheable: This interface extends the Cacheable interface (@see Cacheable) with a method that estimates the size of the Cacheable object, in bytes. CacheManagers constructed with the SizedCacheFactory interface regulate the total estimated cache size, in bytes. CacheManagers constructed with the CacheFactory use regulate the total number of cache entries.
• CacheFactory: A factory for handing out caches.
