This is one of examples ("containment" with "opposite"
association), but generated code depends on model too,
"reference" will be generated in different way and you
need to know model to persist it in the right way
(generated code has meta information). It is not a
good idea to asume generated code implementation, it
must be better to see EMF reflection related stuff
(EObject methods with "e" prefix) and
standard EMF way to integrate custom persistence is
"Resource" API
