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.

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.

void ACE_Null_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES >::minimum CONTAINER &  container,
KEY *&  key_to_remove,
VALUE *&  value_to_remove
[protected]
 

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.Note: Here it is a no-op.
