Class TFTPWriteRequestPacket


public final class TFTPWriteRequestPacket
extends TFTPRequestPacket

A class derived from TFTPRequestPacket definiing a TFTP write request 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.
