Char

Definitions

def digit(radix: { radix = Int32 }, c: Char): Option[Int32]Source

Returns the integer value representated by Char c with respect to radix. E.g. digit(radix = 10, '1') => Some(1) digit(radix = 16, 'a') => Some(11)

Returns None if c does not represent a number.

def forDigit(radix: { radix = Int32 }, n: Int32): Option[Char]Source

Returns a character representation of the integer n with respect to radix. E.g. forDigit(radix = 10, 1) => Some('1') forDigit(radix = 16, 11) => Some('a')

Returns None if n is not representable as single character in the radix.

def getNumericValue(c: Char): Option[Int32]Source

Returns the integer value representated by Char c (e.g. '1' => Some(1)`) or None if c does not represent a number.

This function cannot handle supplementary characters.

def isAscii(c: Char): BoolSource

Returns true if the given char c is an ascii character.

def isAsciiDigit(c: Char): BoolSource

Returns true if the given char c is strictly in the range of ASCII digits 0...9.

def isDefined(c: Char): BoolSource

Returns true if the given char c is defined either as a entry in the UnicodeData file or a value within a range defined in the UnicodeData file.

def isDigit(c: Char): BoolSource

Returns true if the given char c is a recognized Unicode digit. This includes the ASCII range 0..9 but also Arabic-Indic digits, Devagari digits and Fullwidth digits.

def isHexDigit(c: Char): BoolSource

Returns true if the given char c is in the range 0...F.

def isISOControl(c: Char): BoolSource

Returns true if the given char c is an ISO control character.

def isLetter(c: Char): BoolSource

Returns true if the given char c is a letter character.

def isLetterOrDigit(c: Char): BoolSource

Returns true if the given char c is a recognized Unicode letter or digit.

def isLowerCase(c: Char): BoolSource

Returns true if the given char c is lowercase.

def isMirrored(c: Char): BoolSource

Returns true if the given char c is mirrored.

def isOctDigit(c: Char): BoolSource

Returns true if the given char c is in the range 0...7.

def isSurrogate(c: Char): BoolSource

Returns true if the given char c is a surrogate code unit.

def isSurrogatePair(high: { high = Char }, low: { low = Char }): BoolSource

Returns true if the given characters high and low represent a valid Unicode surrogate pair.

def isTitleCase(c: Char): BoolSource

Returns true if the given char c is titlecase, i.e. in the Unicode category of title case letters.

def isUpperCase(c: Char): BoolSource

Returns true if the given char c is uppercase.

def isWhiteSpace(c: Char): BoolSource

Returns true if the given char c is a white space character.

def maxValue(_unit: Unit): CharSource

Returns the character given by the maximum valued byte.

def minValue(_unit: Unit): CharSource

Returns the character given by the all zero byte.

def toBmpCodePoint(c: Char): Int32Source

Returns the code point representation of Char c.

def toLowerCase(c: Char): CharSource

Converts a letter to its lowercase version.

Returns the original character if it does not have a lowercase version.

def toString(c: Char): StringSource

Returns the character c as a string.

def toSupplementaryCodePoint(high: { high = Char }, low: { low = Char }): Int32Source

Returns the supplementary code point value of the surrogate pair high and low.

Caution - this function does no validation, use isSurrogatePair to check high and low are valid.

def toTitleCase(c: Char): CharSource

Converts a letter to its titlecase version.

Returns the original character if it does not have either a titlecase version or a mapping to uppercase.

def toUpperCase(c: Char): CharSource

Converts a letter to its uppercase version.

Returns the original character if it does not have a uppercase version.
