CharacterSet class

a CharacterSet is a collection of characters that is being searched for. e.g. it may contain letters and/or digits and/or other literals. You can also add a range e.g.:

  • 'k-p' (letters k trough p)
  • '2-6' (digits 2 trough 6)

Methods

addDigits() → CharacterSet
See SpecialCharacter.digit Example: var regex=FluentRegex().characterSet(CharacterSet().addDigits()); expect(regex.hasMatch('1'),true); expect(regex.hasMatch('a'),false);
addLetters([CaseType caseType = CaseType.lowerAndUpper]) → CharacterSet
Example: var regex = FluentRegex().characterSet(CharacterSet().addLetters()); expect(regex.hasMatch('a'), true); expect(regex.hasMatch('B'), true); expect(regex.hasMatch('3'), false);
addLineBreaks() → CharacterSet
See SpecialCharacter.carriageReturn and SpecialCharacter.lineFeed Example: expect(regex.findFirst('hello\rworld'), '\r'); expect(regex.findFirst('hello\nworld'), '\n'); expect(regex.findFirst('hello\r\nworld'), '\r\n'); expect(regex.findFirst('hello\r\rworld'), '\r\r'); expect(regex.hasMatch('hello world'), false);
addLiterals(String literalsToAdd) → CharacterSet
Example: var regex = FluentRegex().characterSet(CharacterSet().addLiterals('-')); expect(regex.hasMatch('-'), true); expect(regex.hasMatch(''), true); expect(regex.hasMatch('a'), false);
addNoneDigits() → CharacterSet
See SpecialCharacter.noneDigit Example: var regex=FluentRegex().characterSet(CharacterSet().addDigits()); expect(regex.hasMatch('1'),false); expect(regex.hasMatch('a'),true);
addNoneWhiteSpaces() → CharacterSet
See SpecialCharacter.noneWhiteSpace Example: var regex = FluentRegex().characterSet(CharacterSet().addNoneWhiteSpaces()); expect(regex.hasMatch(' '), false); expect(regex.hasMatch('\u0009'), false); expect(regex.hasMatch('\n'), false); expect(regex.hasMatch('\x0B'), false); expect(regex.hasMatch('\f'), false); expect(regex.hasMatch('\r'), false); expect(regex.hasMatch('h'), true);
addNoneWordChars() → CharacterSet
See SpecialCharacter.noneWordChar Example: var regex=FluentRegex().characterSet(CharacterSet().addNoneWordCharacters()); expect(regex.hasMatch('a'),false); expect(regex.hasMatch('Z'),false); expect(regex.hasMatch('1'),false); expect(regex.hasMatch('!'),true);
addRange(String from, String to) → CharacterSet
Example: var regex = FluentRegex() .characterSet(CharacterSet().addRange('k', 'p').addRange('2', '6')); expect(regex.hasMatch('l'), true); expect(regex.hasMatch('5'), true); expect(regex.hasMatch('a'), false);
addTabs() → CharacterSet
