=head1 DESCRIPTION

Biblio::ILL::ISO::RenewAnswer is a derivation of the abstract
Biblio::ILL::ISO::ISO object, and handles the Renew-Answer message type.

=head1 EXPORT

None.

=head1 ERROR HANDLING

Each of the set_() methods will croak on missing or invalid parameters.

=head1 CONSTRUCTORS

new()

Base constructor for the class. It just returns a completely
empty message object, which you'll need to populate with the
various set_() methods, or use the read() method to read a
Renew-Answer message from a file (followed by a call to
from_asn() to turn the read's returned hash into a proper
RenewAnswer message.

The constructor also initializes the Convert::ASN1 if it
hasn't been initialized.

#---------------------------------------------------------------
sub new {
    my $class = shift;
    my $self = {};

    Biblio::ILL::ISO::ISO::_init() if (not $Biblio::ILL::ISO::ISO::_asn_initialized);
    $self->{"ASN_TYPE"} = "Renew-Answer";

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


#---------------------------------------------------------------

sub as_pretty_string {
    my $self = shift;

    foreach my $key (sort keys %$self) {
	if ($key ne "ASN_TYPE") {
	    print "\n[$key]\n";
	    print $self->{$key}->as_pretty_string();
	}
    }
    return;

#---------------------------------------------------------------
# This will return a structure usable by Convert::ASN1
#---------------------------------------------------------------
sub as_asn {

=head1 METHODS

For any example code, assume the following:
    my $msg = new Biblio::ILL::ISO::RenewAnswer;

=cut

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

=head2 from_asn($href)

To read a message from a file, use the following:

    my $href = $msg->read("msg_14.renew-answer.ber");
    $msg = $msg->from_asn($href);

The from_asn() method turns the hash returned from read() into
a proper message-type object.

=cut

    my $self = shift;
    my $href = shift;

    foreach my $k (keys %$href) {

	    $self->{$k}->from_asn($href->{$k});

	} elsif ($k =~ /^transaction-id$/) {
	    $self->{$k} = new Biblio::ILL::ISO::TransactionId();
	    $self->{$k}->from_asn($href->{$k});

	} elsif ($k =~ /^service-date-time$/) {
	    $self->{$k} = new Biblio::ILL::ISO::ServiceDateTime();
	    $self->{$k}->from_asn($href->{$k});

		 || ($k =~ /^responder-id$/)

	} elsif ($k =~ /^date-due$/) {
	    $self->{$k} = new Biblio::ILL::ISO::DateDue();
	    $self->{$k}->from_asn($href->{$k});

	} elsif ($k =~ /^responder-note$/) {
	    $self->{$k} = new Biblio::ILL::ISO::ILLString();
	    $self->{$k}->from_asn($href->{$k});

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