public final class CharGenTCPClient
extends SocketClient

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.

Constructor Detail

### CharGenTCPClient

    public CharGenTCPClient()

  The default constructor for CharGenTCPClient. It merely sets the default port to `DEFAULT_PORT` .

Method Detail

### getInputStream

    public java.io.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.

  Returns:
    An InputStream from which the server generated data can be read.
