[news.eclipse.modeling.mdt.uml2] Re: Find stereotypes applicable to inst

[Joel Greenyer <jgreen@xxxxxx>]

I solved my problem as follows:

suppose I have EClass eClass and the Stereotype stereotype, then I add all stereotypes applicable to instances of the 
EClass to an array list:

/*
 * When is a stereotye applicable to instances of eClass?
 *
 * 1. when the eClass equals an extended meta-class of the stereotype
 * 2. when the eClass is a subclass of the extended meta-class of the stereotype
 *    <=> the extended meta-class is in the set of superclasses of eClass
 */
ArrayList<Stereotype> applicableStereotypesList = new ArrayList<Stereotype>();
for (Class extendedMetaClass : stereotype.getAllExtendedMetaclasses()) {
	EClassifier eExtendedMetaClass = UMLFactory.eINSTANCE.getEPackage().getEClassifier(extendedMetaClass.getName());
	// 1.
	if (eExtendedMetaClass == eClass){
		applicableStereotypesList.add(stereotype);
		break;
	}
	// 2.
	if (eClass.getEAllSuperTypes().contains(eExtendedMetaClass)){
		applicableStereotypesList.add(stereotype);
		break;
	}
}
