Detailed Description

Id:
Framework_Component.h,v 1.1.1.1 2003/02/21 18:36:32 chad Exp

A prototype mechanism that allows framework components, singletons such as ACE_Reactor, ACE_Proactor, etc, to be registered with a central repository managed by the <ACE_Object_Manager> or <ACE_Service_Config> that will handle destruction.

This technique obviates changing ACE_Object_Manager and ACE_Service_Config everytime a new framework is added. Which also means that unused framework components don't need to linked into the final application which is important for applications with stringent footprint requirements.

Framework components need only provide a static method, close_singleton() and add the ACE_REGISTER_FRAMEWORK_COMPONENT macro call to their instance() methods in order to participate. Components that don't have a close_singleton() method can also participate via template specialization of ACE_Framework_Component_T.

This design uses the External Polymorphism pattern to avoid having to derive all framework components from a common base class that has virtual methods (this is crucial to avoid unnecessary overhead), and is based on the dump debugging implementation found in <ace/Dump.h>.
