Detailed Description

The wcharacter class provides static methods for evaluating and manipulating wide characters.

Member Function Documentation

convertToAscii()

static int32_t wcharacter::convertToAscii ( int32_t  c )

static

Converts "c" to a 7-bit value by clearing the higher order bits.

duplicate() [1/2]

static wchar_t wcharacter::duplicate ( char  c )

static

Returns the wide character representation of character "c" as interpreted by the character set of the current locale.

duplicate() [2/2]

static wchar_t wcharacter::duplicate ( char  c, wchar_t  replacement  )

static

Returns the wide character representation of character "c" as interpreted by the character set of the current locale.

Returns "replacement" if character "c" cannot be converted to a wide character.

duplicateUcs2() [1/4]

static wchar_t wcharacter::duplicateUcs2 ( ucs2_t  c )

static

Returns the wide character representation of UCS-2 character "c".

"c" is presumed to be in the byte-order of the system.

Returns '?' if UCS-2 character "c" cannot be converted to a character.

duplicateUcs2() [2/4]

static wchar_t wcharacter::duplicateUcs2 ( ucs2_t  c, bool  bigendian  )

static

Returns the wide character representation of UCS-2 character "c".

If "bigendian" is true then "c" is presumed to be big endian. If "bigendian" is false, then "c" is presumed to be little endian.

Returns '?' if UCS-2 character "c" cannot be converted to a wide character.

duplicateUcs2() [3/4]

static wchar_t wcharacter::duplicateUcs2 ( ucs2_t  c, wchar_t  replacement  )

static

Returns the wide character representation of UCS-2 character "c".

"c" is presumed to be in the byte-order of the system.

Returns "replacement" if UCS-2 character "c" cannot be converted to a character.

duplicateUcs2() [4/4]

static wchar_t wcharacter::duplicateUcs2 ( ucs2_t  c, wchar_t  replacement, bool  bigendian  )

static

Returns the wide character representation of UCS-2 character "c".

If "bigendian" is true then "c" is presumed to be big endian. If "bigendian" is false, then "c" is presumed to be little endian.

Returns "replacement" if UCS-2 character "c" cannot be converted to a wide character.

getNullSize()

static uint8_t wcharacter::getNullSize ( )

static

Returns the number of bytes needed to NULL-terminate a string of wide characters.

isAlphabetical()

static bool wcharacter::isAlphabetical ( int32_t  c )

static

Returns true if "c" is alphabetical character and false otherwise.

isAlphanumeric()

static bool wcharacter::isAlphanumeric ( int32_t  c )

static

Returns true if "c" is an alphanumeric character and false otherwise.

isAscii()

static bool wcharacter::isAscii ( int32_t  c )

static

Returns true if "c" is one of the values in the ASCII character set or false otherwise.

isBlank()

static bool wcharacter::isBlank ( int32_t  c )

static

Returns true if "c" is a space or tab and false otherwise.

isControlCharacter()

static bool wcharacter::isControlCharacter ( int32_t  c )

static

Returns true if "c" is a control character and false otherwise.

isDigit()

static bool wcharacter::isDigit ( int32_t  c )

static

Returns true if "c" is a digit and false otherwise.

isHexDigit()

static bool wcharacter::isHexDigit ( int32_t  c )

static

Returns true if "c" is a hexadecimal digit and false otherwise.

isInSet()

static bool wcharacter::isInSet ( wchar_t  c, const wchar_t *  set  )

static

Returns true if "c" is in the set of characters in "set" and false otherwise.

isLowerCase()

static bool wcharacter::isLowerCase ( int32_t  c )

static

Returns true if "c" is lower case and false otherwise.

isPrintable()

static bool wcharacter::isPrintable ( int32_t  c )

static

Returns true if "c" is a printable character and false otherwise.

isPrintableNonSpace()

static bool wcharacter::isPrintableNonSpace ( int32_t  c )

static

Returns true if "c" is a printable character other than a space and false otherwise.

isPunctuation()

static bool wcharacter::isPunctuation ( int32_t  c )

static

Returns true if "c" is a printable character that is not a space or alphanumeric character and false otherwise.

isUpperCase()

static bool wcharacter::isUpperCase ( int32_t  c )

static

Returns true if "c" is upper case and false otherwise.

isWhitespace()

static bool wcharacter::isWhitespace ( int32_t  c )

static

Returns true if "c" is any whitespace character and false otherwise.

lower()

static int32_t wcharacter::lower ( int32_t  c )

static

Returns the lower case version of "c".

upper()

static int32_t wcharacter::upper ( int32_t  c )

static

Returns the upper case version of "c".
