ANNOUNCE: Visitor Pattern Posted

[Matthew Heaney <matthew_heaney@acm.org>]

I just posted, to the Patterns list at the ACM, another example of how
to implement the Visitor pattern in Ada95.  The example also explores
some memory management techniques, including a dispatching deallocator.

You can reach the patterns archive by following the links:

<http://www.acm.org/>  --> 
   Search --> 
      Search ACM's LISTSERV Archives  -->
         Patterns -->
           November 1998

Unfortunately, I haven't set up my mailer correctly, so the example I
posted doesn't have a subject.  Just look on the November 1998 page, and
you'll see it.

You can subscribe to the patterns list at ACM by sending the message
body:

to the address <mailto:listserv@acm.org>.

I've been converting the examples in the GoF book to Ada95, and I gave a
brief presentation to the Patterns WG during the SIGAda conference a
couple of weeks ago.  This is some of the material I prepared for that
meeting.
