21 Rose::DB::Object::ConventionManager::Null is a subclass of
22 Rose::DB::Object::ConventionManager that does nothing. That is, it
23 overrides every method with no-ops that always return undef or an empty
24 list, depending on calling context. This class is a singleton.
25
26 When a piece of metadata is missing, the convention manager is asked to
27 provide it. This "null" convention manager class is useful if you do
28 not want the convention manager to provide any information. In other
29 words, use this convention manager class if you want to force all
30 metadata to be explicitly specified.
31
32 See the Rose::DB::Object::ConventionManager documentation for more
33 information on convention managers.
