public final class TFTPErrorPacket extends TFTPPacket
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.
