=head1 NAME

    DBIx::Class::Serialize::Storable - hooks for Storable nfreeze/thaw

=head1 DEPRECATION NOTE

This component is now B<DEPRECATED>. It has not been providing any useful
functionality for quite a while, and in fact destroys prefetched results
in its current implementation. Do not use!

=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 result objects can be
serialized. It assumes that your result 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.
