Re: [aspectj-users] Accessing private fields
|
Alain,
Remember that getDeclaredFields() will only return the fields declared on the class itself, not on its superclasses. If you want all the fields for an instance, you need to walk up the inheritance hierarchy using Class.getSuperclass() and get the declared fields on each.
