| 23 | * The DiscardUDPClient class is a UDP implementation of a client for the |
|
| 24 | * Discard protocol described in RFC 863. To use the class, |
|
| 25 | * just open a local UDP port |
|
| 26 | * with {@link org.apache.commons.net.DatagramSocketClient#open open } |
|
| 27 | * and call {@link #send send } to send datagrams to the server |
|
| 28 | * After you're done sending discard data, call |
|
| 29 | * {@link org.apache.commons.net.DatagramSocketClient#close close() } |
|
| 30 | * to clean up properly. |
