TFTPRequestPacket

java.lang.Object
- org.apache.commons.net.tftp.TFTPPacket
- - 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.

  - newDatagram
```
public final java.net.DatagramPacket newDatagram()
```
    Creates a UDP datagram containing all the TFTP request packet data in the proper format. This is a method exposed to the programmer in case he wants to implement his own TFTP client instead of using the TFTPClient class. Under normal circumstances, you should not have a need to call this method.
    
    Specified by:
    
    newDatagram in class TFTPPacket
    
    Returns:
    
    A UDP datagram containing the TFTP request packet.
