    • isInformational

      public static boolean isInformational(int reply)
      Tests if a reply code is an informational response. All codes beginning with a 1 are positive informational responses. Informational responses are used to provide human-readable information such as help text.
      Parameters:
      reply - The reply code to test.
      Returns:
      True if a reply code is an informational response, false if not.
    • isNegativePermanent

      public static boolean isNegativePermanent(int reply)
      Tests if a reply code is a negative permanent response. All codes beginning with a 5 are negative permanent responses. The NNTP server will send a negative permanent response when it does not implement a command, a command is incorrectly formatted, or a serious program error occurs.
      Parameters:
      reply - The reply code to test.
      Returns:
      True if a reply code is a negative permanent response, false if not.
    • isNegativeTransient

      public static boolean isNegativeTransient(int reply)
      Tests if a reply code is a negative transient response. All codes beginning with a 4 are negative transient responses. The NNTP server will send a negative transient response on the failure of a correctly formatted command that could not be performed for some reason. For example, retrieving an article that does not exist will result in a negative transient response.
      Parameters:
      reply - The reply code to test.
      Returns:
      True if a reply code is a negative transient response, false if not.
    • isPositiveCompletion

      public static boolean isPositiveCompletion(int reply)
      Tests if a reply code is a positive completion response. All codes beginning with a 2 are positive completion responses. The NNTP server will send a positive completion response on the final successful completion of a command.
      Parameters:
      reply - The reply code to test.
      Returns:
      True if a reply code is a positive completion response, false if not.
    • isPositiveIntermediate

      public static boolean isPositiveIntermediate(int reply)
      Tests if a reply code is a positive intermediate response. All codes beginning with a 3 are positive intermediate responses. The NNTP server will send a positive intermediate response on the successful completion of one part of a multipart command or sequence of commands. For example, after a successful POST command, a positive intermediate response will be sent to indicate that the server is ready to receive the article to be posted.
      Parameters:
      reply - The reply code to test.
      Returns:
      True if a reply code is a positive intermediate response, false if not.
