Set base class of custom stereotype in MDG Technology Profile

[ea0220]

Hi,

I have several stereotypes extending object and want to create a custom toolbox so that I can drag and drop object instances of a certain class(es).
Is there an option to set the stereotype's base class so that these objects are instances of a certain class?
And if this option exists, how can I do that?

Example:
Let's say I have a Testcase stereotype extending object. Can I change that so that each Testcase object is an instance of my class Testcase?

Background is that I'd like to drag and drop object instances of certain classes using a custom toolbox.

No, you can't.

You are mixing meta-model with model elements. Your "certain" classes are not meta-classes but regular model classes, which you can't access in your meta-model.

The best you can do is link your instance stereotype with your classifier stereotype.
If you then drag a element of your classifier stereotype onto a diagram and choose to drop is as an instance, it will automatically get the instance stereotype.

What you are wanting to do is the same thing as SysML does with Unit and QuantityKind.

It's not quite as easy (for you or your users) as a simple stereotype, but it can be done.

You need:

• A model wizard pattern for the actual classes that you want included in the user model.
• A pattern for an instance of one of those classes
• Add <technologyname>::<patternname>(UMLPatternSilent) to your toolbox. (You can also use UMLPattern so the dialog shows)
• Users will need to import the model pattern and then they should be able to use the toolbox item.

Thanks for the answers.

Considering the necessary steps and the ease of use for end users we'll refrain from that approach.
