public static String getDirectiveValue(HashMap<String,String> directivesMap,
                                       String directive,
                                       boolean mandatory)
                                throws AuthenticationException

Throws:

AuthenticationException

copyDirective

public static String copyDirective(HashMap<String,String> directives,
                                   StringBuilder sb,
                                   String directive)

Copy the directive to the StringBuilder if not null.

copyDirective

public static String copyDirective(HashMap<String,String> src,
                                   HashMap<String,String> dst,
                                   String directive)

Copy the directive to the from src to dst if not null.

parseDirectives

public static HashMap<String,String> parseDirectives(byte[] buf)
                                              throws SaslException

Parses digest-challenge string, extracting each token and value(s)

Parameters:

buf - A non-null digest-challenge string.

Throws:

UnsupportedEncodingException

SaslException - if the String cannot be parsed according to RFC 2831

isLws

public static boolean isLws(byte b)

Is character a linear white space ? LWS = [CRLF] 1*( SP | HT ) Note that we're checking individual bytes instead of CRLF

Parameters:

b - the byte to check

Returns:

true if it's a linear white space

stringTo8859_1

public static String stringTo8859_1(String str)
                             throws UnsupportedEncodingException

Used to convert username-value, passwd or realm to 8859_1 encoding if all chars in string are within the 8859_1 (Latin 1) encoding range.

Parameters:

str - a non-null String

Returns:

a non-null String containing the 8859_1 encoded string

Throws:

AuthenticationException

UnsupportedEncodingException

getSingleValuedHeader

public static String getSingleValuedHeader(Map<String,List<String>> headers,
                                           String key)

addValueToHeader

public static void addValueToHeader(Map<String,List<String>> headers,
                                    String key,
                                    String value,
                                    boolean singleValued)
