new Problem on applieng a StereoType [message #474274]

Hello NG, hello James ;)
at first I want to congratulate James for his "upgrade" ;)
Well, here is my problem. I have two methods. One is creating a Package
with some classes and the other creates a Package with some stereotypes.
Now I want to apply a StereoType to a Class after creating both
Packages. I tried it as follows:

Package classes = createClassDiagramPackage();
Class classA = getElementByName(Class.class, classes, CLASS_A_NAME);
Package stereoTypes = createStereoTypePackage();
Stereotype st = getElementByName(Stereotype.class, stereoTypes,
STEREOTYPE_TEST);
classA.applyStereotype(st);

But all I get is IllegalArgumentException when applieng the StereoType.
My method getElementByName looks like this:

public static <T extends NamedElement> T getElementByName(
java.lang.Class<T> klasse, Package owningPackage, String name) {
EList<Element> elements = owningPackage.allOwnedElements();
for (Element element : elements) {
if (klasse.isInstance(element)) {
String tempName = ((NamedElement)element).getName();
if (tempName.equals(name)) {
return klasse.cast(element);
}
}
}
return null;
}

This method works fine - that means I don't get null as result. So why
can't I apply the StereoType?

Hello Jan,

AFAIK stereotypes needs to be defined within a profile, and you have to
apply this profile to your package "classes" before you can apply
stereotypes to its classes.

You can still have a look at
http://www.eclipse.org/modeling/mdt/uml2/docs/articles/Intro duction_to_UML2_Profiles/article.html

There might have some changes since this article but the learning about
profile and stereotypes is still good

Regards,
Philippe

Hmm...If I construct a model with the UML Model Editor you can just
apply a StereoType to a Class without having any Profile. Then you can
right-click the root and Validate the Model without problems. So can
anybody approve that a Profile is needed?

Hi Jan,

Thanks for the congrats on the "upgrade" :)

In general, you would need to "define" your profile before actually using it
( unless you are using static profile definition but that's another story ).
Profiles are a way of extending an existing metamodel. Some ecore
representation (dynamic or static) would be needed before they can be used.
Profiles are generally created in a separate resource since they could be
reused.

In terms of creating a stereotype in a package without "define" and without
a "profile" ...it doesn't seem like that should work. I gave it a quick
try in the UML editor and was unable to correctly reference a metaclass or
apply the sterotype to some other element. Could you provide step by step
instructions and I will give it a try.

The getting started article would be the best starting point and indicates
the "traditional" way of working with profiles ( as Philippe pointed out ).

Cheers,

- James.
