Re: [emf-dev] Making Classes and Reference in Ecore of arbitrary Java ty

[Michael Olsen <cmolsen@xxxxxxxxxx>]

Ed,

OK. This is my first posting. Newbie,
I guess is the term for someone like me. I'll the newsgroup you suggested.
 

But since I have you involved already...

Let me reiterate what it is I want to
do; namely to extend the Thread class so I can add my own methods to the
class. I need a class for this, not an attribute. I know how to subclass
manually in the Java implementation, but I'd like to keep my Ecore model
"up to par" with the implementation.  

I'm aware that EMF can be used to create
arbitrary DataTypes, and I am using this feature already.  But that
doesn't suffice for what I want to do now.

The EMF book is of little help to me
in this case. Can you help?

Regards,

Michael, 

Please use the newsgroup for questions rather than the mailing list.  

I don't think it makes much sense to have a Thread be an EObject, and you
won't get it to work anyway because your generated classes will extend
EObjectImpl and if they extended Thread, they wouldn't be able to implement
the EObject/InternalEObject API easily.   It sounds more likely that
you would want an EDataType (5.5.2) with instance class Thread so that
you can have attributes of type Thread.

Subject	[emf-dev] Making Classes and Reference in Ecore of arbitrary Java types

I'm designing my ecore model using the Direct approach (using the EMF ecore
editor.) 

I would like to declare some of my classes as java.lang.Thread and java.nio.ByteBuffer.

But it seems that the only types I can assign to my classes is limited
to the standard EMF types (e.g., EObject, EClassifier,...).

I read chapter 5.5 in the EMF book, but it didn't help me.

Is it even possible to declare a class of, say, type java.lang.Thread,
which when generated will extend the Thread class so I can subclass it
and add my own thread methods? 

Can you help? 

Sincerely,
