=head1

=head2 new( $date [, $renewable] )

Creates a new DateDue object.
 Expects a date string (YYYYMMDD), and
 (optionally) a "renewable" flag string ("true"/"false").

=cut
sub new {
    my $class = shift;
    my $self = {};

    if (@_) {
	my ($date, $renewable) = @_;

	croak "missing date" unless ($date);
	$renewable = "true" unless (defined $renewable);

	$self->{"date-due-field"} = new Biblio::ILL::ISO::ISODate($date);
	$self->{"renewable"} = new Biblio::ILL::ISO::Flag($renewable);
    }

    bless($self, ref($class) || $class);
    return ($self);
}


#---------------------------------------------------------------
#
#---------------------------------------------------------------
=head1

=head2 set( $date [, $renewable] )

Sets the object's date-due-field (a date string (YYYYMMDD)), and
 (optionally) a "renewable" flag (a string ("true"/"false")).

=cut
sub set {
    my $self = shift;
    my ($date, $renewable) = @_;

    croak "missing date" unless ($date);
    $renewable = "true" unless (defined $renewable);

    $self->{"date-due-field"} = new Biblio::ILL::ISO::ISODate($date);
    $self->{"renewable"} = new Biblio::ILL::ISO::Flag($renewable);

    return;
}

#---------------------------------------------------------------
#
#---------------------------------------------------------------
=head1

=head2 from_asn($href)

Given a properly formatted hash, builds the object.

=cut
sub from_asn {
    my $self = shift;
    my $href = shift;

    foreach my $k (keys %$href) {
	#print ref($self) . "...$k\n";

	if ($k =~ /^date-due-field$/) {
	    $self->{$k} = new Biblio::ILL::ISO::ISODate($href->{$k});

	} elsif ($k =~ /^renewable$/) {
	    $self->{$k} = new Biblio::ILL::ISO::Flag($href->{$k});

	} else {
	    croak "invalid " . ref($self) . " element: [$k]";
	}

    }
    return $self;
}
