All Implemented Interfaces:

CachedIF

public class CacheManager
extends java.lang.Object
implements CachedIF

INTERNAL: A manager class that manages cached objects. Cached objects can be registered with the cache manager in order to follow the life cycle set by the environment using the cache manager. The cached objects must implement the CachedIF interface.

Note that this class also implements the CachedIF interface, so that it can itself be fully refreshed and also be managed by other cache managers.
