I would like to execute some custom code in order to additionally modify the EMF model before save. Is it possible with Sirius?

Thanks!

Hi Tamas,

There are several ways to do this with EMF or Sirius mecanisms.
It mainly depends on what you want to detect and when/how to react.

You might use a precommit listener (org.eclipse.emf.transactionResourceSetListener configured in precommit, aggregate or not) or use a org.eclipse.sirius.business.api.session.ModelChangeTrigger (has a notion of priority and trigger predicate plus a notion of priority which allows them to be called regarding the priority and not the installation order (case of the resource set listener).

Could you give more details about the changes you want to detect and the kind of model modification you want to do ?

You might find samples of both mecanisms in
https://github.com/ObeoNetwork/UML-Designer/blob/master/plugins/org.obeonetwork.dsl.uml2.design/src/org/obeonetwork/dsl/uml2/design/internal/listeners/UmlDesignerSessionManagerListener.java

Hi Maxime,

Thanks for your quick reply!

Actually, the custom code should be executed only if the model is changed by the Sirius editor (on save) and should not be executed if the model is changed via an external event (e.g: on a git revert).

The org.eclipse.sirius.business.api.session.ModelChangeTrigger looks promising, I will give it a try.

Regards,
Tamás
