Detailed Description

template<class KEY, class VALUE, class CONTAINER, class ITERATOR, class ATTRIBUTES>
class ACE_Refcounted_Recyclable_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES >

Defines a helper class for the Caching Strategies.

This class defines the methods commonly used by the different caching strategies. For instance: clear_cache () method which decides and purges the entry from the container.

Note

This class helps in the caching_strategies using a container containing entries of <Refcounted_KEY, Recyclable_Connection_Handler> kind. The attributes helps in deciding the entries to be purged. The Cleanup_Strategy is the callback class to which the entries to be cleaned up will be delegated.

Purge entries from the container. The Cleanup_Strategy will do the actual job of cleanup once the entries to be cleaned up are decided.
