    Re: global constants - two alternatives...

    My concern goes beyond 'unused symbols'. I'm trying to make sense of a coding standard that suggests using the 'global_constants1' option.

    Re: static factory...

    Again - from my perspective a Dn handler does not need a notification when a Pn message is updated by a Pn handler. A Dn handler's process method is invoked after 'Reads' of Aircraft (A/C) data. ...

    Re: static factory...

    OK! Let me rethink this.

    Here's another question: Assume the messages were singleton.

    Given:


    D1* ptr2 = static_cast< D1* > ( simple.GetInstance ( 1 ) );

    This results in a call to:
