    • addProtocolCommandListener

      public void addProtocolCommandListener(ProtocolCommandListener listener)
      Adds a ProtocolCommandListener.
      Parameters:
      listener - The ProtocolCommandListener to add.
    • fireCommandSent

      public void fireCommandSent(String command, String message)
      Fires a ProtocolCommandEvent signalling the sending of a command to all registered listeners, invoking their protocolCommandSent() methods.
      Parameters:
      command - The string representation of the command type sent, not including the arguments (e.g., "STAT" or "GET").
      message - The entire command string verbatim as sent to the server, including all arguments.
    • fireReplyReceived

      public void fireReplyReceived(int replyCode, String message)
      Fires a ProtocolCommandEvent signalling the reception of a command reply to all registered listeners, invoking their protocolReplyReceived() methods.
      Parameters:
      replyCode - The integer code indicating the natureof the reply. This will be the protocol integer value for protocols that use integer reply codes, or the reply class constant corresponding to the reply for protocols like POP3 that use strings like OK rather than integer codes (i.e., POP3Repy.OK).
      message - The entire reply as received from the server.
    • getListenerCount

      public int getListenerCount()
      Returns the number of ProtocolCommandListeners currently registered.
      Returns:
      The number of ProtocolCommandListeners currently registered.

    • removeProtocolCommandListener

      public void removeProtocolCommandListener(ProtocolCommandListener listener)
      Removes a ProtocolCommandListener.
      Parameters:
      listener - The ProtocolCommandListener to remove.
