public static ClassTransferResponseMessage decodeTransferResponse(int messageID,
                                                                  ASN1Element element)
                                                           throws SLAMDException

Decodes the provided ASN.1 element as a class transfer request message.

Parameters:

messageID - The message ID to use for this message.

element - The ASN.1 element containing the encoded class name.

Returns:

The class transfer request message decoded from the ASN.1 element.

Throws:

SLAMDException - If the provided ASN.1 element cannot be decoded as a class transfer request message.

encode

public ASN1Element encode()

Encodes this message into an ASN.1 element. A file transfer response message has the following ASN.1 syntax:

ClassTransferResponse ::= [APPLICATION 13] SEQUENCE { responseCode INTEGER, className OCTET STRING, classData OCTET STRING }

Specified by:

encode in class Message

Returns:

An ASN.1 encoded representation of this message.
