public final class TFTPWriteRequestPacket extends TFTPRequestPacket
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.
