how to link references [message #1060330]

In the Graphiti tutorial references among objects of the model, which in the tutorial is an instance of the ECORE meta-meta-model, are stored via a EReference instance like this

link(connection, addedEReference);

The problem is that in the instance of my own ECORE meta-model references ar just properties of the involved meta-classes. How should I link these to the related connections?

Regards

Andrea,

you may link to the source and/or target instance of the object containing
the reference. Additionally you may store the name of the reference as a
name-value-property along with the connection (e.g. in case there are
several references that might connect the 2 objects).

Hi,

you could also link the connection to the "feature" which it represents.

E.g. XPackage.Literals.XX_YY : EReference

With this connection you can handle everything when the connection is selected, I think.

See the thread under [1] for a more detailed explanation.
