class ACE_Cache_Map_Manager< KEY, VALUE, CMAP_TYPE, ITERATOR_IMPL, REVERSE_ITERATOR_IMPL, CACHING_STRATEGY, ATTRIBUTES >

Defines a abstraction that will purge entries from a map.

The <ACE_Cache_Map_Manager> will manage the map it contains and provide purging on demand from the map. The strategy for caching is decided by the user and provided to the Cache Manager. The Cache Manager acts as a agent and communicates between the Map and the Strategy for purging entries from the map. No locking mechanism provided since locking at this level isn't efficient. Locking has to be provided by the application.
