Hi all,

I generate code from Papyrus UML-based models. Now, I would like to do it incrementally, i.e., each time the user changes the model and saves it I would like to determine which UML classes are affected by changes and regenerate code only for these classes.
Here is my question: is it possible to know what has changed before Papyrus saves the model? I am especially interested in structural model changes, not the diagrams.

Thanks for your support!
Wladimir

Yes it is possible you can connect a listener that can listenr all action in the model.
you have to implement a org.eclipse.papyrus.core.listenerservice.IPapyrusListener
and fill the extension point org.eclipse.papyrus.core.modelListener

for example in org.eclipse.papyrus.diagram.common plugin:
<extension
point="org.eclipse.papyrus.core.modelListener">
<listener
description="This listener listens for profile (un)applications to update the palette"
name="PaletteProfileApplicationListener"
realization=" org.eclipse.papyrus.diagram.common.service.PaletteProfileApp licationListener ">
</listener>
</extension>
