=head1 NAME
KiokuDB::TypeMap::Entry::DBIC::Row - KiokuDB::TypeMap::Entry for DBIx::Class::Row objects.
=head1 VERSION
version 1.23
=head1 DESCRIPTION
L<DBIx::Class::Row> objects are resolved symbolically using the special ID
format:
dbic:row:$json
The C<$json> string is a serialization of:
[ $result_source_name, @primary_key_values ]
The row objects are not actually written to the KiokuDB storage, as they are
already present in the other tables.
Looking up an object with such an ID is a dynamic lookup that delegates to the
L<DBIx::Class::Schema> and resultsets.
