Get all elements with stereotype X applied [message #797293]

Hi,

I am looking for a comfortable way to get all elements within a UML model with a certain stereotype X applied.

		EList<Element> list = model.allOwnedElements();
		for (Element e : list) {
			if (e.isStereotypeApplied(X)) {
				System.out.println(e);
			}
		}

Is this the only way? Or is there a more comfortable alternative?

Regards,

Michael

Hi Michael,
maybe not more comfortable but faster is this way:

for (EObject ob : resourceModel.getContents()) {
if (ob instanceof DynamicEObjectImpl) {
if (((DynamicEObjectImpl)ob).eClass().getName().equals("X")) {
for (EObject feature : ob.eClass().getEAllStructuralFeatures()) {
if (feature instanceof EReference) {
if (((EReference)
feature).getName().startsWith(Extension.METACLASS_ROLE_PREFIX)) {
Object appliedUMLElement = ob.eGet((EStructuralFeature) feature);
if (appliedUMLElement != null) {
System.out.println(appliedUMLElement); }
else{
System.out.println("broken Stereotype "+ob);
}break;
}
}

}
}
}
}

Hi Michael

This doesn't help you today, but I consider many of the difficulties in
the use of profiles to be a bug in at least Eclipse OCL and probably the
OMG OCL specification too. The OCL model loading environment should make
models available in a form that makes navigation easy for OCL and for
tools that can exploit OCL.

Michael,

Your code won't actually find elements with the stereotype applied, but
rather the elements to which the stereotype is applicable (i.e., could
legally be applied). You'd want to use the
Element#isStereotypeApplied(Stereotype) operation.

Another more direct, and possibly more efficient, way of doing this (but
which relies more on the underlying implementation details) would be to
iterate over the contents of the resource(s) containing the elements,
looking for stereotype applications using UMLUtil#getStereotype(EObject)
and, upon finding ones that correspond to the stereotype in question,
retrieve (and rememeber) their "base" elements using
UMLUtil#getBaseElement(EObject).
