My understanding is that an EMF generated model implementation can have
either java attributes, or virtual attributes. By virtual I mean
attributes that are not defined in java code, but give rise to accessible
slots in an EObject which can be accessed via eSet and eGet. Is it
possible to generate an EMF model implementation such that all the
generated attributes are virtual? Clearly this is not the most efficient
way of accessing slot values, but it does provide a more unified protocol
and it would remove the need to override eSet and eGet in subclasses of
EObject.

Sorry Ed. I intended to post to the EMF newsgroup, but posted here by
accident. I use the simple web newsgroup access and was unsure how to
remove this post.
Thanks for your answer - that was helpful.

James,
Answering questions is less work for me if postings to multiple
newsgroup are done with a single posting. This way, an answer on any of
the newsgroups will appear on all of the newsgroups. Here's what I said
on the EMF newsgroup:
You can mark a feature as being volatile, and in that case the
generator will generate only stub methods that you must implement by
hand.
