Can we determine incoming connections from the impl? [message #199295] Mon, 28 July 2008 20:04 Go to next message

I'm trying to setup some validation rules, and want to ensure that every
node on my diagram has an incoming connection? Is there a way from the
impl to get the incoming connections if they exist?

This would also be useful in my future to make sure that certain nodes
have a particular type of node as a "parent" in the tree..., though the
parent can have * different types as children.

Thanks in advance

Hi, Brian,

The GMF runtime automatically adds a CrossReferenceAdapter to your
resource set. You can use the API that it defines (and that it
inherites from ECrossReferenceAdapter in EMF) to find objects that
reference some target object using a given EReference.

HTH,

Christian
