Class DaytimeUDPClient
DatagramSocketClient
org.apache.commons.net.daytime.DaytimeUDPClient
public final class DaytimeUDPClient
extends DatagramSocketClient
The DaytimeUDPClient class is a UDP implementation of a client for the
Daytime protocol described in RFC 867. To use the class, merely
open a local datagram socket with
open
and call
getTime
to retrieve the daytime
string, then
call
close
to close the connection properly. Unlike
DaytimeTCPClient
,
successive calls to
getTime
are permitted
without re-establishing a connection. That is because UDP is a
connectionless protocol and the Daytime protocol is stateless.
