I'm working on a project consisting of two Eclipse plugin projects. One is an EMF project and contains the metamodel for the application. The other one is the acctual plugin working on that metamodel.
I'm now looking for a way to list all types of models available in the metamodel project. Since I basically need all generated classes I could use reflections to iterate through the metamodel package but I'd prefer an easier way if there is one.
The models are already listed as extensions in the plugin.xml
like this:
<plugin>
<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri="MyModel"
class="org.myproject.metamodel.MyModel.MyModelPackage"
genModel="model/MetaModel.genmodel"/>
</extension>
</plugin>
where the class MyModelPackage
extends EPackage
and org.myproject.metamodel.MyModel
also contains all the other generated classes I need to list. I'm guessing that I can use that information but I still don't know how.
Update
The project I'm working on is based on EMFStore. Running it offers the EMFStore perspective. If I have the Navigator view with a project I can right click on that project and select New Model Element
. This opens a dialog where all the model elements from my metamodel are listed so it is possible. It must be done somewhere in EMFStore or one of it's dependencies. I looked through the source code but can't seem to find where it's done.
The plugin.xml
of the project org.eclipse.emf.emfstore.perspective
refers to the class org.eclipse.emf.emfstore.emfperspective.EMFStorePerspective
which I can't find in the sources. I imported the project via the Eclipse Import Plug-Ins and Fragments functionality and it has no source folder. In the EMFStore git repositories I can't even find that project.
Update
I now got the registry that contains the generated packages using EPackage.Registry.INSTANCE
. Unfortunately it contains more than the EPackages from the one project containing the metadata (org.myproject.metamodel
). Now I'm just looking for a proper way to filter it, but still can't get the hang of it.
Update
As the filtering is not part of my original question I accepted the answer by @SpaceTrucker. For those who are curious, this is how I've done it now:
Registry registry = EPackage.Registry.INSTANCE;
for (String key : new HashSet<String>(registry.keySet())) {
EPackage ePackage = registry.getEPackage(key);
if (ePackage.getClass().getName().startsWith("org.myproject.metamodel")) {
//do stuf
}
}
I found no way to filter for the project but luckily all the packages start with the same prefix.
