How to resolve opposite end of an UML Extension ? [message #476264]

Hi,

I'm using a ResourceSetListener to react on postcommit changes to my
editing domain (containing UML models).

Now I want to react on a Stereotype application to model elements, but
all I get in
ResourceSetChangeEvent#getTransaction().getChangeDescription () is a
DynamicEObjectImpl which references the EClass of the Stereotype
definition - which makes sense for the UML extension mechanism.

My Problem now is: How do I process this DynamicEObject and how do I get
access to the opposite end of the extension (e.g. the UML element the
stereotype was actually applied to) ?
Or should there be more information elsewhere (e.g. searching through
all the Notifications) ?

Thanks for any hints,
kind regards,
Florian

Hi Florian,

There are several helpers you can find in UMLUtil.

Have a look at UMLUtil.getBaseElement() and UMLUtil.getStereotype().

Pass the stereotype application that you have your hands on and you will get
back the items you are looking for.

Cheers,

- James.
