Re: OOD, Ada, and Inheritance

[emery@mitre-bedford.arpa (David Emery)]

Ada *does* provide a limited form of inheritance, via derived types.
Ada 9X will build on this for general inheritance.  

We've 'simulated' inheritance via generics.  This was a painful
process.  

Generally, if inheritance makes sense, then use it in the design, and
'manually code' it.  If all you need is inheritance, and not
polymorphism, that's easy to do.  Polymorphism requires a lot of case
analysis, which is somewhat more painful.

Finally, you might want to consider 'Classic-Ada', which is a
pre-processor that takes an "object oriented Ada" and translates it to
legal Ada.
