Connect to the Resource [message #378356]

Hi,
I am trying to listen to the changes made to the sematic model behind
the GMF editor. I have noticed that the EMF resources can be listened,
and they can notify of the changes intervening in their elements when
isNotificationTrackerEnabled() is set to true.

Should I try to listen to the resource ? If so, where is the best place
to plug in ?
Maybe GMF provides a plugin extension point to do such things ?

Do you have any implementation of such a behaviour ?

Anoine,

This is an EMF (or GMF question) so best to use that (those)
newsgroup(s). The resource will only notify for direct changes to the
getContents of that resource (or it's other direct features). You
probably want to use something like an EContentAdapter, which you can
attached to a resource, resource set, or EObject. It will listen to
every object in the containment tree and will attach and removed itself
as the content tree changes.
