- * A final class derived from TFTPPacket definiing the TFTP Data

- * packet type.

- * <p>

- * 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

- * {@link org.apache.commons.net.tftp.TFTPClient} class

- * {@link org.apache.commons.net.tftp.TFTPClient#receiveFile receiveFile()}

- * and

- * {@link org.apache.commons.net.tftp.TFTPClient#sendFile sendFile()}

- * methods.
