in EMF Java API, you can remove EObjects from Java models with
EcoreUtil.delete(EObject eObject, boolean recursive) service. Indicating
a recursive delete is prefered for deleting references to contained objects.
notice that the java model will be no more valid when some eobjects are
deleted. e.g. if you delete some private method, some MethodInvocation
instances pointing to it from one java statement will be invalid. It may
not be important in your use case if you do not care of Java statements
in method bodies.

I solved it by creating a specific deletion query, corresponding to a
selection query. However, if it was possible to execute a query on all
the objects, in the table, i.e. allow multiple selection as is possible
in the main view, I could use a generic deletion query on the result of

Yes, that makes it possible to avoid duplicating code.
