Class TFTPAckPacket
public final class TFTPAckPacket
A final class derived from TFTPPacket definiing the TFTP Acknowledgement
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.

TFTPAckPacket
public TFTPAckPacket(InetAddress destination,
int port,
int blockNumber)
Creates an acknowledgment packet to be sent to a host at a given port
acknowledging receipt of a block.
destination
- The host to which the packet is going to be sent.port
- The port to which the packet is going to be sent.blockNumber
- The block number being acknowledged.
getBlockNumber
public int getBlockNumber()
Returns the block number of the acknowledgement.
- The block number of the acknowledgement.
newDatagram
public DatagramPacket newDatagram()
Creates a UDP datagram containing all the TFTP
acknowledgement 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 acknowledgement packet.
setBlockNumber
public void setBlockNumber(int blockNumber)
Sets the block number of the acknowledgement. **
