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 an Answer message from a file (followed by a call to from_asn() to turn the read's returned hash into a proper Answer message.

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

METHODS

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

from_asn($href)

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

my $href = $msg->read("msg_04.answer.ber");
$msg = $msg->from_asn($href);

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

set_protocol_version_num($pvn)

Sets the protocol version number.
Acceptable parameter values are the strings:
   version-1
   version-2

set_transaction_id($tid)

 Sets the message's transaction-id.  
 Expects a valid Biblio::ILL::ISO::TransactionId.

    my $tid = new Biblio::ILL::ISO::TransactionId("PLS","001","", 
					          new Biblio::ILL::ISO::SystemId("MWPL"));
    $msg->set_transaction_id($tid);

 This is a mandatory field.

   my $sdt = new Biblio::ILL::ISO::ServiceDateTime( $dt_this, $dt_orig);
   $msg->set_service_date_time($sdt);

This is a mandatory field.
