## Class PrintCommandListener

- java.lang.Object
- - org.apache.commons.net.PrintCommandListener

- All Implemented Interfaces:
    EventListener, ProtocolCommandListener

      public class PrintCommandListener
      extends Object
      implements ProtocolCommandListener

  This is a support class for some of the example programs. It is a sample implementation of the ProtocolCommandListener interface which just prints out to a specified stream all command/reply traffic.

  Since:
    2.0
