=head1 NAME
KiokuDB::Backend::Serialize::JSPON::Collapser - Collapse entry data to JSPON compliant structures
=head1 VERSION
version 0.57
=head1 SYNOPSIS
my $c = KiokuDB::Backend::Serialize::JSPON::Collapser->new(
id_field => "_id",
);
my $hashref = $c->collapse_jspon($entry);
=head1 DESCRIPTION
This object is used by L<KiokuDB::Backend::Serialize::JSPON> to convert
L<KiokuDB::Entry> objects to JSPON compliant structures.
=head1 ATTRIBUTES
See L<KiokuDB::Backend::Serialize::JSPON::Converter> for attributes shared by
L<KiokuDB::Backend::Serialize::JSPON::Collapser> and
L<KiokuDB::Backend::Serialize::JSPON::Expander>.
=head1 METHODS
=over 4
=item collapse_jspon $entry
Collapses the entry recursively, returning a JSPON compliant data structure
suitable for serialization as a JSON string.
