createClass and createOwnedClass [message #759329]

Mon, 28 November 2011 06:56

Hi,

what's the difference between UMLFactory.eINSTANCE.createClass() and
org.eclipse.uml2.uml.Model::createOwnedClass() ? Why they both exist?
Same question can be related to UMLFactory.eINSTANCE.createAssociation()
and org.eclipse.uml2.uml.Class::createAssociation()

Thanks in advance

Hi

XXXFactory.eINSTANCE.createYYY() is the standard EMF functionality to
create a naked YYY.

org.eclipse.uml2.uml.Model::createOwnedClass() has some context, so I
preume it establishes the result as an ownedClass.

Regards

Yes. In fact you can look at the implementation to see what it does, so
no presumption is required...
