org.eclipse.persistence.internal.oxm.Reference
INTERNAL:
Purpose: Holds mapping reference info. The info held in this class will be used after unmarshal to resolve 1-1 and 1-M mapping references. This is necessary to ensure that all related objects have been created before attempting to set instance values in related objects.
