36    DBIx::Class::Serialize::Storable - hooks for Storable freeze/thaw
37
38=head1 SYNOPSIS
39
40    # in a table class definition
41    __PACKAGE__->load_components(qw/Serialize::Storable/);
42
43    # meanwhile, in a nearby piece of code
44    my $cd = $schema->resultset('CD')->find(12);
45    # if the cache uses Storable, this will work automatically
46    $cache->set($cd->ID, $cd);
47
48=head1 DESCRIPTION
49
50This component adds hooks for Storable so that row objects can be
51serialized. It assumes that your row object class (C<result_class>) is
52the same as your table class, which is the normal situation.
53
54=head1 HOOKS
55
56The following hooks are defined for L<Storable> - see the
57documentation for L<Storable/Hooks> for detailed information on these
58hooks.
59
60=head2 STORABLE_freeze
61
62The serializing hook, called on the object during serialization. It
63can be inherited, or defined in the class itself, like any other
64method.
65
66=head2 STORABLE_thaw
67
68The deserializing hook called on the object during deserialization.
