I'm adding some global actions, and needed to figure out how to get at all the EObjects. So here is the code that I came up with, which works for my particular application. If you have some enhancements please feel encouraged to post.

EditingDomain editingDomain = ((IEditingDomainProvider)activeEditorPart).getEditingDomain( );
// get the root
Resource res = editingDomain.getResourceSet().getResources().get(0);
if (res instanceof XMIResourceImpl){
XMIResourceImpl xmi = (XMIResourceImpl) res;
TreeIterator<EObject> iter =xmi.getAllContents();
for (;iter.hasNext(); ) {
EObject ob = (EObject)iter.next();
}
}

Don't you want to handle all resources? ResourceSet.getAllContents()
might be helpful; note that it yields resources and their contents...

You're only interested in XMI resources?

Note that any given resource might contain objects with references that
are unresolved proxies. EcoreUtil.resolveAll helps ensure that all
proxies are resolve.
