Class TFTPErrorPacket
public final class TFTPErrorPacket
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.

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.
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.
getError
public int getError()
Returns the error code of the packet.
- The error code of the packet.
getMessage
public String getMessage()
Returns the error message of the packet.
- The error message of the packet.
newDatagram
public DatagramPacket newDatagram()
Creates a UDP datagram containing all the TFTP
error packet data in the proper format.
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.
- newDatagram in interface TFTPPacket
- A UDP datagram containing the TFTP error packet.
