Hi,

I'd like to be able to show inherited associations.

Looking at the attached image, I'd like to show the inherited property in class C as an inherited association, marked similar to the inherited property.

Is it possible?

Hello,

This is not possible since the association can not be inherited, only the property can.

Best regards,
Pauline

Hi

Are you sure that it is just 'inherited' that you want to see? UML has no first class support for the polymorphism that we are familiar with as virtual in C++ or Java. Rather it has some redefinition scaffolding that allows you to emulate standard and very dubious inheritance idioms.

What I want to achieve is a way to (in another diagram) show that Class C has a property b of type Class B in the form of an association(aggregation).

See the attached image.

The reason for this is that I might create a base class with a number of aggregated classes displayed in a diagram.

When I specialize this bas class and add more associated classed I want the classes from the base class to be show as well.
