Hi,
i work with Magritte framework for define more data about one specific
problem.
Now some data is defined as subclass of another class.
[...]
My questions are :
A) What's the best method for not replicate the SuperClass descriptions ?
You just add the descriptions for the new attributes to the
subclasses. Descriptions are inherited.
B) If i need to change the label of the priority of
one of SuperClass
description how i can do it ?
Override the superclass method with the modified description.
C) When i need to do copy of one description and after
send to the copy
specific messages ?
D) When i have a specific description,
for example descriptionNazionality based on MASingleOptionDescription,
and i have in the "data base" some reference to it ,
i can define only one basic descriptionNationality and use it ( or copy
of it ) with specific attribute ( label priority accessor ) ?
I don't understand what you want to do. Maybe
http://onsmalltalk.com/programming/smalltalk/using-magritte-with-seaside/
can give you some hints?
What's the solution for have the best
performance ? ( I think to port
it to GLASS )
I'd advise you to program the solution that is the simplest to
program. Maybe the performance of that solution is completely OK for
your application. For persistence, see also
