=head1 NAME
KiokuDB::TypeMap::Entry::Passthrough - A typemap entry of objects that will be serialized by the backend.
=head1 VERSION
version 0.57
=head1 SYNOPSIS
KiokuDB::TypeMap->new(
entires => {
'Value::Object' => KiokuDB::TypeMap::Entry::Naive->new,
},
);
=head1 DESCRIPTION
This typemap entry delegates the handling of certain objects to the backend.
A prime example is L<DateTime> being handled by
L<KiokuDB::Backend::Serialize::Storable>. L<DateTime> has efficient L<Storable>
hooks, and does not refer to any domain objects, so it is safe to assume that
it can just be passed through for serialization.
=head1 ATTRIBUTES
=over 4
=item intrinsic
If true the object will be just left in place.
If false, the object will get its own ID and entry, and the object will be in
the C<data> field of that entry.
