NAME

       Rose::DB::Object::ConventionManager::Null - A singleton convention manager that does
       nothing.

SYNOPSIS

         package My::Product;

         use Rose::DB::Object;
         our @ISA = qw(Rose::DB::Object);

         # This really sets the convention manager to a
         # Rose::DB::Object::ConventionManager::Null object
         __PACKAGE__->meta->convention_manager(undef);
         ...

DESCRIPTION

       Rose::DB::Object::ConventionManager::Null is a subclass of
       Rose::DB::Object::ConventionManager that does nothing.  That is, it overrides every method
       with no-ops that always return undef or an empty list, depending on calling context.  This
       class is a singleton.

       When a piece of metadata is missing, the convention manager is asked to provide it.  This
       "null" convention manager class is useful if you do not want the convention manager to
       provide any information.  In other words, use this convention manager class if you want to
       force all metadata to be explicitly specified.

       See the Rose::DB::Object::ConventionManager documentation for more information on
       convention managers.
