Hi,

I'm looking for small examples that make use of EContentAdapter.

I would be interested to know how to get notified of any object creation
that occurs in a given subtree of the model.

Many thanks, Adelino.

Adelino,

We don't have any examples of this. It's pretty simple to use. Just
create a derived class EContentAdapter class, override
notifyChanged(Notification notification) being sure to call super, and
add it to any object using eObject.eAdapters().add(new
MyEContentAdapter()). You'll get notifications from all objects in the
tree.

Hello Ed

I tried attaching an EContentAdapter to my resource to listen to
notifications (i eventually want to listen to addition of child
elements) like this:
resource.eAdapters().add(myNotificationAdapter);

It works ok for all elements directly under the root element but not for
any deeper level.

Is there anything i need to do to make it 'notify' element changes deep
within the tree ?

thanks

roy

Roy,

It should attach itself to the whole tree. You are sure you are calling
super in your notifyChanged override? If you look at the deeper
children's eAdapters() list, are they empty or do the contain the
EContentAdapter instance?
