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 FTP server will send a negative permanent response on the failure of a command that cannot be reattempted with success.- 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 FTP server will send a negative transient response on the failure of a command that can be reattempted with success.- 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 FTP 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 FTP server will send a positive intermediate response on the successful completion of one part of a multipart sequence of commands. For example, after a successful USER command, a positive intermediate response will be sent to indicate that the server is ready for the PASS command.- Parameters:
reply
- The reply code to test.- Returns:
- True if a reply code is a positive intermediate response, false if not.
-
isPositivePreliminary
public static boolean isPositivePreliminary(int reply) Tests if a reply code is a positive preliminary response. All codes beginning with a 1 are positive preliminary responses. Postitive preliminary responses are used to indicate tentative success. No further commands can be issued to the FTP server after a positive preliminary response until a follow-up response is received from the server.- Parameters:
reply
- The reply code to test.- Returns:
- True if a reply code is a positive preliminary response, false if not.
-
isProtectedReplyCode
public static boolean isProtectedReplyCode(int reply) Tests if a reply code is a protected response.- Parameters:
reply
- The reply code to test.- Returns:
- True if a reply code is a protected response, false if not.
- Since:
- 3.0
