Detailed Description

template<class ATTRIBUTES, class CACHING_UTILITY, class IMPLEMENTATION>
class ACE_Caching_Strategy_Adapter< ATTRIBUTES, CACHING_UTILITY, IMPLEMENTATION >

This class follows the Adaptor pattern and is used to provide External Polymorphism by deriving from ACE_Caching_Strategy.

This class simply delegates all requests to the IMPLEMNETATION object within. This class should be passed in place of the the abstract base ACE_Caching_Strategy class as part of the External Polymorphism pattern.
