Extending the Graphiti Metamodel [message #1110166]

Hi there,

I would like to know which of these two solutions may be the good one to
extend the Graphiti Metamodel concepts from the package "pictograms".
For example, I want to introduce a new concept "MyCustomContainerShape"
which is a particular "ContainerShape" with new attributes and references.

I think about two solutions :

I - Extending the Graphiti Metamodel

In this solution, I choose to develop an extension of the Graphiti
Metamodel whith the new concept: MyCustomContainerShape
-> ContainerShape -> Shape (-> for extending).

Then, once the ecore created, I generate the code of my custom factory
with the gen model referencing the graphiti genmodel.

Finally, in my addFeature code, I use both the peCreateService and my
own factory to create either Shape / Container Shape or MyCustomContainer.

II - Creating a new uncoupled Metamodel

In my second solution, I choose to design a new metamodel with my new
concept: MyCustomContainerShape.

Then, in my addFeature code, I create a ContainerShape, a
MyCustomContainerShape, and link the Container Shape to both the
MyCustomContainerShape and the BusinessObject. This gives the following
scheme:

Business Object --- Pictogram Container Shape --- MyCustomContainerShape
(--- is a link) where :

- Business Object is my Business Object serialized in my Business Model
Resource ;
- Pictogram Container Shape is the Graphiti Container Shape serialized
in my Diagrame Resource ;
- MyCustomContainerShape is my new concept serialized in my Diagram
Resource, enhancing the Container Shape with attributes et references.

Is one of these two solutions may be implementable ?

Thanks in advance,

Regards,

Hi,

Thanks a lot,

This is exactly what I was looking for and I was hoping that the
metamodel extension solution was better solution than adding link with
an uncoupled metamodel.
