Hi all,

Is it possible to use the UMLFactory to create an object from the String
representation of its type? For example, I want to create a new class
using "org.eclipse.uml2.uml.Class".

Thanks a lot for your help!

This is more of an EMF question. The API you want is
EPackage#getEClassifier(String) and EFactory#create(EClass).

In the case of UML2, this would do the trick:

EObject aClass =
UMLFactory.eInstance.create(
UMLPackage.eInstance.getEClassifier(
"org.eclipse.uml2.uml.Class"
)
);

Cheers,

Rafael

Thank you so much for your help! I managed to create UML objects. Is there
a way to set the ID of the object? I usually get the ID by calling:

eobject.eResource().getURIFragment(eobject)

But eResource is of course null after creating the object the way I did.

Iris,

The extrinsic IDs are managed by the resource so until you add the new
object to a resource (directly or indirectly by adding it to a
containing object already in a resource) it won't have an ID.
