Detailed Description

template<class KEY, class VALUE, class CONTAINER, class ITERATOR, class ATTRIBUTES>
class ACE_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 <KEY, HANDLER> kind where the HANDLER contains the caching attributes which help 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.

template<class KEY, class VALUE, class CONTAINER, class ITERATOR, class ATTRIBUTES> ACE_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES >::ACE_Handler_Caching_Utility (  ACE_Cleanup_Strategy< KEY, VALUE, CONTAINER > *    cleanup_strategy = 0, int    delete_cleanup_strategy = 0 )

Constructor.

template<class KEY, class VALUE, class CONTAINER, class ITERATOR, class ATTRIBUTES> ACE_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES >::~ACE_Handler_Caching_Utility (  void    )

Destructor.

template<class KEY, class VALUE, class CONTAINER, class ITERATOR, class ATTRIBUTES> ACE_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES >::ACE_Handler_Caching_Utility (  const ACE_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES > &    )  [private]

Member Function Documentation

template<class KEY, class VALUE, class CONTAINER, class ITERATOR, class ATTRIBUTES> int ACE_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES >::clear_cache (  CONTAINER &    container, double    purge_percent )

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

template<class KEY, class VALUE, class CONTAINER, class ITERATOR, class ATTRIBUTES> void ACE_Handler_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.

template<class KEY, class VALUE, class CONTAINER, class ITERATOR, class ATTRIBUTES> void ACE_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES >::operator= (  const ACE_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES > &    )  [private]

Member Data Documentation

template<class KEY, class VALUE, class CONTAINER, class ITERATOR, class ATTRIBUTES> CLEANUP_STRATEGY_BASE* ACE_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES >::cleanup_strategy_ [protected]

The cleanup strategy which can be used to destroy the entries of the container.

template<class KEY, class VALUE, class CONTAINER, class ITERATOR, class ATTRIBUTES> int ACE_Handler_Caching_Utility< KEY, VALUE, CONTAINER, ITERATOR, ATTRIBUTES >::delete_cleanup_strategy_ [protected]

Whether the cleanup_strategy should be destroyed or not.
