public final class TFTPErrorPacket
extends TFTPPacket
A final class derived from TFTPPacket definiing the TFTP Error packet type.

Details regarding the TFTP protocol and the format of TFTP packets can be found in RFC 783. But the point of these classes is to keep you from having to worry about the internals. Additionally, only very few people should have to care about any of the TFTPPacket classes or derived classes. Almost all users should only be concerned with the TFTPClient class receiveFile() and sendFile() methods.

Constructors

 o TFTPErrorPacket
 public TFTPErrorPacket(InetAddress destination,
                        int port,
                        int error,
                        String message)
Creates an error packet to be sent to a host at a given port with an error code and error message.

Parameters:
destination - The host to which the packet is going to be sent.
port - The port to which the packet is going to be sent.
error - The error code of the packet.
message - The error message of the packet.

Methods

 o newDatagram
 public DatagramPacket newDatagram()
This is a method exposed to the programmer in case he wants to implement his own TFTP client instead of using the TFTPClient class. Under normal circumstances, you should not have a need to call this method. It creates a UDP datagram containing all the TFTP error packet data in the proper format.

Returns:
A UDP datagram containing the TFTP error packet.
Overrides:
newDatagram in class TFTPPacket
 o getError
 public int getError()
Returns the error code of the packet.

Returns:
The error code of the packet.
 o getMessage
 public String getMessage()
Returns the error message of the packet.

Returns:
The error message of the packet.
