I would need to get the EditingDomain and the ResourceSet from and IFile
without opening that file in the EMF editor?
I don't know if that question even makes sense or not, but is that
possible? I have multiple files which I need to add things
programmatically, so I need the resourceset to find the owner where to add
my new nodes and I need the editing domain to execute the AddCommand I
create.
With one file, I got everything by opening the editor, but I don't know if
I can modify files that aren't even opened?
