 * @class ACE_Framework_Component_T
 *
 * @brief This class inherits the interface of the abstract 
 * ACE_Framework_Component class and is instantiated with the 
 * implementation of the concrete component class <class Concrete>.
 *
 * This design is similar to the Adapter and Decorator patterns
 * from the ``Gang of Four'' book.  Note that <class Concrete>
 * need not inherit from a common class since ACE_Framework_Component
 * provides the uniform virtual interface!  (implementation based on 
 * ACE_Dumpable_Adapter in <ace/Dump_T.h>.
