Hi OCL Community,
I want to represent OCL query for Coupling between Objects: Basically coupling between class counts a number of other classes to which the class is coupled. Classes are coupled when methods are declared in one class use attribute of other classes.
Any body have an idea, how to calculate this in OCL, I am using EMF model to execute my queries.
Thanks in advance.
Albert

Hi Albert
If you use more precise language, you will find it quite easy and
perhaps impossible without redefinition.
A coupling is the size of the couplings, which is a set of classes.
The couplings of a class C is the union of the couplings of all the
operations of C excluding C.
The couplings of an operation C::O is the union of the
referredProperty.class of all PropertyCallExp within the operation body
excluding C.
?? what about the transitive call hierarchy ??
?? what about overridden methods that have extended coupling ??
Regards
Ed Willink
