Class CharGenTCPClient
public final class 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.

CharGenTCPClient
public CharGenTCPClient()
The default constructor for CharGenTCPClient. It merely sets the
default port to DEFAULT_PORT
.
getInputStream
public InputStream getInputStream()
Returns an InputStream from which the server generated data can be
read. You should NOT close the InputStream when you're finished
reading from it. Rather, you should call
disconnect
to clean up properly.
- An InputStream from which the server generated data can be read.
