EEnum to Epackage relationship lost [message #73745] Tue, 06 March 2007 13:35 Go to next message

Hello,
I have a condition where I have an EPackage(OriginPackage) with some
EClassifiers in it.

Now using Dynamic EMF we are trying to create a new package with details
from OriginPackage like EClassifiers,name,uri,nsURI.

Code Snipplet:

for (Iterator iter = oldSubpackage.getEClassifiers().iterator();
iter.hasNext();) {

// Object container = element.getEClassifiers().get(i);
Object container = iter.next();
if (container instanceof EClass) {
EClass newClass = EcoreFactory.eINSTANCE.createEClass();
newClass.setName("_" + ((EClass) container).getName());
newClass.getESuperTypes().add(container);
newSubPackage.getEClassifiers().add(newClass);
} else {
EEnum tempEnum = EcoreFactory.eINSTANCE.createEEnum();
tempEnum.setName(((EEnum) container).getName());
tempEnum.getELiterals().addAll(((EEnum) container).getELiterals());
newSubPackage.getEClassifiers().add(tempEnum);
}
}


When this code is executed for the EEnum classifiers the EPackage is not
set. That is if i try to do eenum.getEPackage() it return null.


Any solutions?

Prateek,

It looks like this code wouldn't work if the EClassifier is an
EDataType. It also looks like you will move the EEnumLiterals from the
original to the copy; you should use EcoreUtil.copy to copy each
literal. It should not be possible for tempEnum to have no containing
EPackage after you add it to the classifiers of a package. What's the
value of EObject.eContainer() and EObject.eContainmentFeature() for it?
