[gme-users] Ordering of sets in Bon

[Jacques Kerner]

Hi,

I would like to know how the std::set<...> returned by BONExtender 
generated functions are ordered. For instance, I have a model named 
"Container" that aggregates "Contained" Atoms "contained1", "contained2" 
and "contained3" and I was uable to figure out how the ordering was 
made. Sometimes the order is by creation of the contained elements, 
sometimes not, ...

Is there a way to impose the ordering on the returned sets ? Do I have 
to define a specific operator < for this ? Could BonExtender generate 
one from a rule in the meta model ?

I also wondered if one can retrieve the position of elements in diagrams 
in BON .

Thank you in advance.

Jacques Kerner.
