  • About logic in the formation of the inclusion of header files.

    I apologize. Maybe I'm not a great connoisseur of C ++ and ACE. I can not understand: why is it necessary to include in ace\Event_Handler.h a forward declaration like

    class ACE_Reactor;

    instead #include "ace\Reactor.h"?

    When I inherit from ACE_Event_Handler like this

    class ClientAcceptor : public ACE_Event_Handler {...}

    I'm sure I need to include the header file ace\Event_Handler.h in which the ACE_Event_Handler class is defined. But, it turns out, I must also include ace\Reactor.h.
