=head1 NAME
DBIx::Class::Serialize::Storable - hooks for Storable freeze/thaw
=head1 SYNOPSIS
# in a table class definition
__PACKAGE__->load_components(qw/Serialize::Storable/);
# meanwhile, in a nearby piece of code
my $cd = $schema->resultset('CD')->find(12);
# if the cache uses Storable, this will work automatically
$cache->set($cd->ID, $cd);
=head1 DESCRIPTION
This component adds hooks for Storable so that row objects can be
serialized. It assumes that your row object class (C<result_class>) is
the same as your table class, which is the normal situation.
=head1 HOOKS
The following hooks are defined for L<Storable> - see the
documentation for L<Storable/Hooks> for detailed information on these
hooks.
=head2 STORABLE_freeze
The serializing hook, called on the object during serialization. It
can be inherited, or defined in the class itself, like any other
method.
=head2 STORABLE_thaw
The deserializing hook called on the object during deserialization.
