=head1 DESCRIPTION

=cut

package qpid::proton;


=pod

=head2 MAPS

Moving values from a map within a B<qpid::proton::Data> object into a
Perl B<Hash> object is done using the following:

=over

=item %hash = qpid::proton::get_map_from( [DATA] );

=back

=cut

sub get_map_from {
    my $data = $_[0];

    die "data cannot be nil" unless defined($data);

    my $type = $data->get_type;

    die "current node is not a map" if !($type == qpid::proton::MAP);

    my $result;
    my $count = $data->get_map;

    $data->enter;
    for($i = 0; $i < $count/2; $i++) {
        $data->next;
        my $type = $data->get_type;
        my $key = $type->get($data);
        $data->next;
        $type = $data->get_type;
        my $value = $type->get($data);
        $result{$key} = $value;
    }
    $data->exit;

    return $result;
}
