    • sendMessage

      public void sendMessage(String message) throws IOException
      Send a String to the instantiated connection.

      This method throws an IOException so the server or servlet holding the connection open can respond to the exception if there is an immediate failure. If there is an asynchronous failure, the connection is closed.

      Parameters:
      message - message to send
      Throws:
      IOException - if problem sending message

    • close

      public void close() throws IOException
      Close the connection.

      Note: Objects using JmriConnection with a Session may prefer to use getSession().close() since Session.close() does not throw an IOException.

      Throws:
      IOException - if problem closing connection
