Detailed Description

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

Defines a dummy 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 is be used with the Null_Caching_Strategy. The Cleanup_Strategy is the callback class to which the entries to be cleaned up will be delegated.

int ACE_Null_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.

Note:

Here it is a no-op.

Find the entry with minimum caching attributes. This is handler specific since this utility is to be used very specifically for handler who have caching_attributes for server side acched connection management.

Here it is a no-op.
