Re: [henshin-dev] Exported Packages in org.eclipse.emf.henshin.model

[Christian Krause <henshin.ck@xxxxxxxxx>]

Hi Jürgen,

instead of reimplementing the methods again, ideally the generated implementation classes should inherit from Henshin's NodeImpl class. If EMF does not do this automatically, you can try to use the @extends tag in the user doc section of your generated implementation classes. Usually this is used for adding interfaces, but maybe it works also for superclasses. I did not find much information about it, you can take a look at https://www.faktorzehn.org/de/en/dokumentation/manuelle-anpassungen-des-generieten-codes/ or the EMF book.

If the extends tag does not work, you could use a custom EMF template to generate it in this way.

If this also doesn't work, you need to reimplement the methods I guess, as you are doing it now. I added the actions package to the exports. You can pull the latest sources from git or fetch a nightly build. For reference, here is the corresponding Gerrit change: https://git.eclipse.org/r/#/c/53760/

Cheers,

Christian

Hi Christian,

so I made a model which has some classes that inherit from a Henshin node.

When I generate the model into Java then I have some unimplemented methods.
e.g.: public Action getAction()

My first implementation of these methods is just a copy from the
implemented methods within the henshin model.

The above mentioned method uses
NodeActionHelper.INSTANCE.getAction(this); for the body. This class is
within the org.eclipse.emf.henshin.model.actions package which is not
exported from the Henshin manifest file.

So I get the following error:
Access restriction: The method
'GenericActionHelper<Node,Rule>.getAction(Node)' is not API (restriction
on required project 'org.eclipse.emf.henshin.model')


Greets,
Jürgen
