How do you extend a PrimitiveType? [message #1738910]

Hello,
I'm trying to create a Money Type derived from an UML PrimitiveType such as Real.
Can you do that in Papyrus 2.0?

Hi

You can in UML and I see no reason why it should be a problem in Papyrus.

However PrimitiveTypes are primitive and so IMHO it would be much better
to use a DataType, with a <<Real>> stereotype from OCLforUML.

Prior to OCLforUML, it was necessary for OCL tooling to try to deduce
whether an XXX::Boolean was the same type as a YYY::Boolean e.g. SysML /
UML / OCL / Ecore / ...) and so I extended the pragmatism that
CollectionType specializations are equal by local name regardless of
their namespace to treat PrimitiveTypes as equal regardless of their
namespace. Consequently your MoneyType PrimitiveType is on the way to
being equal to someone else's MoneyType PrimitiveType. Better not to use
PrimitiveTypes for non-primitive concepts.

Regards

Ed Willink

I've applied the OCLforUML Profile to my model, created a Money DataType and applied the Real Stereotype to the latter. It worked. Many thanks, Ed.
