Hi
I have an object of class A, wich has 0 or many objects of class B.
Object B has an attribute called x, wich is an enum.
An object A can have many objects of class B, but each object B inside A must have a differente value for its attribute x.
I know how to model that an object of class A has 0 or many objects of type B, using composition inside a class diagram, but how do i model the above restriction?
Thanks
