static String |
copyDirective(HashMap<String,String> src,
HashMap<String,String> dst,
String directive)
Copy the directive from the source map to the destination map, if it's
value isn't null.
|
static void |
copyDirective(HashMap<String,String> directives,
StringBuilder sb,
String directive)

StringBuilder if not null. |
static String |
getDirectiveValue(HashMap<String,String> directivesMap,
String directive,
boolean mandatory)
A directive is a parameter of the digest authentication process.
|
static String |
getSingleValuedHeader(Map<String,List<String>> headers,
String key)
Returns the value of the named header.
|
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
|
static HashMap<String,String> |
parseDirectives(byte[] buf)

|
static String |
stringTo8859_1(String str)
