Member Function Documentation template int std::collate< _CharT >::compare (const _CharT * __lo1, const _CharT * __hi1, const _CharT * __lo2, const _CharT * __hi2) const [inline], [inherited] Compare two strings. This function compares two strings and returns the result by calling collate::do_compare(). Parameters __lo1 Start of string 1. __hi1 End of string 1. __lo2 Start of string 2. __hi2 End of string 2. Returns 1 if string1 > string2, -1 if string1 < string2, else 0. template int std::collate< _CharT >::do_compare (const _CharT * __lo1, const _CharT * __hi1, const _CharT * __lo2, const _CharT * __hi2) const [protected], [virtual], [inherited] Compare two strings. This function is a hook for derived classes to change the value returned. See also compare(). Parameters __lo1 Start of string 1. __hi1 End of string 1. __lo2 Start of string 2. __hi2 End of string 2. Returns 1 if string1 > string2, -1 if string1 < string2, else 0. References std::forward(). template long std::collate< _CharT >::do_hash (const _CharT * __lo, const _CharT * __hi) const [protected], [virtual], [inherited] Return hash of a string. This function computes and returns a hash on the input string. This function is a hook for derived classes to change the value returned. Parameters __lo Start of string. __hi End of string. Returns Hash value. References std::forward(). template collate< _CharT >::string_type std::collate< _CharT >::do_transform (const _CharT * __lo, const _CharT * __hi) const [protected], [virtual], [inherited] Transform string to comparable form. This function is a hook for derived classes to change the value returned. Parameters __lo Start. __hi End. Returns transformed string. References std::forward(). template long std::collate< _CharT >::hash (const _CharT * __lo, const _CharT * __hi) const [inline], [inherited] Return hash of a string. This function computes and returns a hash on the input string. It does so by returning collate::do_hash(). Parameters __lo Start of string. __hi End of string. Returns Hash value. template string_type std::collate< _CharT >::transform (const _CharT * __lo, const _CharT * __hi) const [inline], [inherited] Transform string to comparable form. This function is a wrapper for strxfrm functionality. It takes the input string and returns a modified string that can be directly compared to other transformed strings. In the C locale, this function just returns a copy of the input string. In some other locales, it may replace two chars with one, change a char for another, etc. It does so by returning collate::do_transform(). Parameters __lo Start of string. __hi End of string. Returns Transformed string_type. Member Data Documentation template locale::id std::collate< _CharT >::id [static], [inherited] Numpunct facet id.
