| startsWithIgnoreCase | | public static boolean startsWithIgnoreCase(String s, String prefix)(Code) | | Like String.startsWith, but case-insensitive.
|
| unescape | | public static String unescape(String subject, char escapeChar, String metachars, String chars, boolean keepUntranslatedEscapes)(Code) | | Translate escape sequences (e.g. \r, \n) to characters.
Parameters:
subject - String in which metacharacters are to be escaped
Parameters:
escapeChar - the escape character (e.g., \)
Parameters:
metachars - letters representing escape codes (typically "btrn\\")
Parameters:
chars - characters corresponding to metachars (typically "\b\t\r\n\\").Must have chars.length () == metachars.length().
Parameters:
keepUntranslatedEscapes - Controls behavior on unknown escape sequences(see below). subject where every escapeChar followed by c in metacharsis replaced by the character corresponding to c in chars. If an escapesequence is untranslatable (because escapeChar is followed by some character cnot in metachars), then the escapeChar is kept if keepUntranslatedEscapes is true,otherwise the escapeChar is deleted. (The character c is always kept.) |
