      extended by org.apache.commons.net.tftp.TFTPRequestPacket
Direct Known Subclasses:
TFTPReadRequestPacket, TFTPWriteRequestPacket

public abstract class TFTPRequestPacket
extends TFTPPacket

An abstract class derived from TFTPPacket definiing a TFTP Request packet type. It is subclassed by the TFTPReadRequestPacket and TFTPWriteRequestPacket classes.

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.
