[news.eclipse.tools.uml2] Re: Extending UML2

["saurabh" <8bholas@xxxxxxxxxx>]

hi Tas,

I read below about the extension of  UML2, I just wanted to ask you a few 
questions
I have been trying to extend UML2 and I am able to extend my metamodel using 
UML2. I can generate the code and everything works fine. I am still not able 
to use all the UML2 capabilities for example, I have a my meta class called 
FocusArea which extends UMLPackage , when i create the instance i use 
factory.createFocusArea();
and then add it to the resource. I make FocusArea behave like a UMLPackage 
using
a 1...many ChildFocusArea reference of type FocusArea, so when i generate 
the code i could use  FocusArea.createChildFocusArea(), I could also use 
UMLPackage.createPackage()...and add a child FocusArea that way but when i 
do that it is persisted in the resource as UMLPackage. I will have mixed 
content in this case, I have a UI which uses the aboveAPI , what i am really 
looking for is , when i call factory.getFocusArea() it should return me the 
instance
of a UML2Package , this way adding it to resource will mean i have pure UML2 
content. Do you understand wha i am trying to say..? Please also look
at my post on "UML persistance" on the 14/07/06 in the group, i would really 
appreciate if i could get some pointers as i am stuck here.
