Package com.oroinc.net
Class CharGenTCPClient
java.lang.Object
com.oroinc.net.SocketClient
com.oroinc.net.CharGenTCPClient
The CharGenTCPClient class is a TCP implementation of a client for the
character generator protocol described in RFC 864. It can also be
used for Systat (RFC 866), Quote of the Day (RFC 865), and netstat
(port 15). All of these protocols involve connecting to the appropriate
port, and reading data from an input stream. The chargen protocol
actually sends data until the receiving end closes the connection. All
of the others send only a fixed amount of data and then close the
connection.
To use the CharGenTCPClient class, just establish a connection with connect and call getInputStream() to access the data. Don't close the input stream when you're done with it. Rather, call disconnect to clean up properly.
