Hi
I'm reading the EMF book (new edition), and I couldn't figure out how to
implement a MapEntry in the ecore file. In particular, I'm referring to
page 270, the IntToOrderMapEntry.
As far as I understand, there is no direct support for <<MapEntry>>
stereotype in ecore models, am I right? If so, I don't think this is
made explicit in the book...
then, how to define a MapEntry class in ecore?
thanks in advance
Lorenzo

Ecore itself has no concept of stereotypes; that's just a Rose notation
for it.

The first paragraph describes how it's represented in Ecore, i.e, an
EClass with the instance class name set to java.util.Map$Entry.

This FAQ entry should help:

I see... is there any plan to add it to ecore (or at least a way of
directly specifying a Map entry in ecore)?

thanks! I should have checked it before... I trusted google which
however didn't point to the FAQs ;)

There is already a way to specify it.

Sometimes the trick is to know what term to search, which of course
doesn't help when you don't know. :-P

sorry, I meant a more "direct" way, instead of specifying the class
instance and manually add the key and value fields...
cheers

Lorenzo,
No, there are no plans to add non-essential features to Ecore itself.
Tools might well provide convenient notations, but that's it...

Hi Ed
sorry again for not being clear: I actually meant whether tools will
provide a more "direct" way; and with tools I mean, e.g., the ecore tree
editor or the ecorediag editor (by the way, is the ecorediag editor part
of EMF now?).
cheers

The Ecore Tools project is part of EMFT. I don't plan to do anything
and I don't think Ecore Tools does either.
