class
NNTPReply
extends Object
NNTPReply stores a set of constants for NNTP reply codes. To interpret
the meaning of the codes, familiarity with RFC 977 is assumed.
The mnemonic constant names are transcriptions from the code descriptions
of RFC 977. For those who think in terms of the actual reply code values,
a set of CODE_NUM constants are provided where NUM is the numerical value
of the code.

public static boolean isInformational(int reply)
Determine 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.
public static boolean isNegativePermanent(int reply)
Determine 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.
public static boolean isNegativeTransient(int reply)
Determine 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.
public static boolean isPositiveCompletion(int reply)
Determine 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 postive completion response, false
if not.
public static boolean isPositiveIntermediate(int reply)
Determine 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 multi-part 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 postive intermediate response, false
if not.
