Package com.oroinc.net
Class DaytimeUDPClient
java.lang.Object
com.oroinc.net.DatagramSocketClient
com.oroinc.net.DaytimeUDPClient
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.
