## Class DiscardTCPClient

- java.lang.Object
- - org.apache.commons.net.SocketClient
  - - org.apache.commons.net.discard.DiscardTCPClient

- Direct Known Subclasses:
    EchoTCPClient

      public class DiscardTCPClient
      extends SocketClient

  The DiscardTCPClient class is a TCP implementation of a client for the Discard protocol described in RFC 863. To use the class, merely establish a connection with `connect` and call `getOutputStream()` to retrieve the discard output stream. Don't close the output stream when you're done writing to it. Rather, call `disconnect` to clean up properly.
