[gme-users] OCL question

[Shravana Musunuri]

Actually the two models are not directly related. How to do in such a
case?

Thanks

It's easiest if the two models are related in some way. Example:

 



 

Constraint Context: Atom1

 

Constraint Expression: self.connectedFCOs("dst", Atom2)->forAll(atom2 :
Atom2 | self.attr1 < atom2.attr2)

 

In English: "The value of the att1 field of every Atom1 instance must be
greater than the att2 fields of every Atom2 instance to which it is
linked
by a Connection1 connection."

 

Hope that helps,

Matt

Hi,

     Can anyone let me know how we could set a constraint on an

attribute of a model (A) to be less than the value of an attribute in

other model (B)? Till now I'be been using only the "self" command to set

constraints on the attributes of particular model. I've used OCL fns and

set the constraint on the parent model itself ( which setved my

purpose), but I am curious to know how to access another model's

attributes in OCL.

 

Thanks

 

Shravana
