Method Detail
-
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.
