Multiple Inheritance: select which Impl java class will be used as superclass [message #478300] Mon, 13 April 2009 14:30 Go to next message

Hello all,

I have a class (CustomElement) that inherits from PackageElement and from
one of my classes (BaseCustomElement). When CustomElementImpl is
generated, it has PackageableElement as superclass. Is there a way to
instruct the generator to use BaseCustomElementImplo as superclass?

Thanks in advance.
Best regards,
Cristi.

Hi Cristian,

If you change the order of the ESuper Types in the ecore representation of
CustomElement such that BaseCustomElement appears first then it should work.
Select the 'CustomElement' in the tree view, then from the properties view
select 'ESuper Types' field. Use the 'Up' & 'Down' keys from the property
dialog to change the order.

Cheers,
- James.

.... from the .uml model, you can reorder your generalizations such that the
one for BaseCustomElement appears first using drag/drop in the tree editor.
When it comes time to convert the .uml model to .ecore, you will see an
option labeled 'Super Class Order'. Simply choose either 'ignore' or
'report' but *not* 'process'. If you choose 'process' it may reorder the
superclass order to optimize for code generation.

Cristian,

If to set a keyword of "extend" on a generalization using
Element#addKeyword(String), the general class will become the base
superclass when the UML model is converted to Ecore.
