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.

int ACE_Refcounted_Recyclable_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES >::clear_cache ( CONTAINER &  container,

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

Find the entry with minimum caching attributes.

This figure denotes the number of entries are there in the container which have been marked as closed already but might not have been unbound from the container.
