Hi all,
I created a UML profile that has a stereotype (e.g. S1) with a property (s2_reference) that refers to another stereotype (S2). An example:
|-------------------------|
|<<Stereotype>> |
| S1 |
|-------------------------|
|label: String |
|s2_ref: S2 |
|-------------------------|
This stereotype is applied to a NamedElement in UML and I'm able to set the property value for types like String, Boolean, Integer. Example for property label, this code works:
namedElement.setValue(S1, labelProperty.getName, "Some String Object");
However, I'm not sure how to create an object for stereotype S2 in order to set value for property s2_ref:
namedElement.setValue(S1, s2refProperty.getName, ??);
I have tried to get to get an EObject:
EObject s2Object = s1.getStereotypeApplication(s2);
But this returns null. How do I create an instance of stereotype S2?
Many thanks,
Rajiv

Hi, Rajiv,
I think you might rather use the Profile::create(Classifier) API only
for creating instances of Classes defined in your profile. Instances
of Stereotypes must always be applied to some element in the model, and
the way to do that is by either taking the result of the
Element::applyStereotype(Stereotype) method or
Element::getStereotypeApplication(Stereotype) for a stereotype that is
already applied.
The procedure that you sketched in your post will result in a dangling
instance of the S2 stereotype that isn't applied to any element.

Right, with a Class you're all set then, Rajiv.
Enjoy!
