How to make a class a singleton [message #1085364]

I have a class I've described in ECore that I'd like to be a singleton class. Is this possible in ECore/EMF?

So, instead of executing:

ProjectsFactory.eINSTANCE.createWorkspaceManager();

I would execute:

ProjectsFactory.eINSTANCE.getWorkspaceManager();

or even better:

WorkspaceManager.getWorkspaceManager();

Ken,

Certainly you can add such things by hand, but there's no way to
generate it. It's always possible to create more than one instance of
any non-abstract EClass...
