39 =head1 DESCRIPTION
40
41 This component adds hooks for Storable so that row objects can be
42 serialized. It assumes that your row object class (C<result_class>) is
43 the same as your table class, which is the normal situation. However,
44 this code is not yet well tested, and so should be considered
45 experimental.
