Parameters:

messageID - The message ID for this message.

responseCode - The response code that indicates whether the class information has been provided.

className - The name of the class file associated with this class transfer response message.

classData - The encoded class data.

Method Detail

getResponseCode

public int getResponseCode()

Retrieves the response code associated with this message. The value will be that of one of the MESSAGE_RESPONSE_* constants.

Returns:

The response code associated with this response message.

getClassName

public java.lang.String getClassName()

Retrieves the Java class name associated with this class transfer response message.

Returns:

The Java class name associated with this class transfer response message.

getClassData

public byte[] getClassData()

Retrieves the encoded class data associated with this class transfer response.

Returns:

The encoded class data associated with this class transfer response.

toString

public java.lang.String toString()

Retrieves a string representation of this message.

Overrides:

toString in class Message

Returns:

A string representation of this message.

decodeTransferResponse

public static ClassTransferResponseMessage decodeTransferResponse(int messageID,
                                                                  ASN1Element element)

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.
