This facet encapsulates the code to compare strings in a localized manner. The collate template uses protected virtual functions to provide the actual results. The public accessors forward the call to the virtual functions. These virtual functions are hooks for developers to implement the behavior they require from the collate facet.

Constructor & Destructor Documentation template std::__cxx11::collate< _CharT >::collate (size_t __refs = 0) [inline], [explicit] Constructor performs initialization. This is the constructor provided by the standard. Parameters __refs Passed to the base facet class. template std::__cxx11::collate< _CharT >::collate (__c_locale __cloc, size_t __refs = 0) [inline], [explicit] Internal constructor. Not for general use. This is a constructor for use by the library itself to set up new locales. Parameters __cloc The C locale. __refs Passed to the base facet class. template virtual std::__cxx11::collate< _CharT >::~collate () [inline], [protected], [virtual] Destructor. Member Function Documentation template int std::__cxx11::collate< _CharT >::compare (const _CharT * __lo1, const _CharT * __hi1, const _CharT * __lo2, const _CharT * __hi2) const [inline] 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] 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. template long std::collate< _CharT >::do_hash (const _CharT * __lo, const _CharT * __hi) const [protected], [virtual] 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. template collate< _CharT >::string_type std::collate< _CharT >::do_transform (const _CharT * __lo, const _CharT * __hi) const [protected], [virtual] 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. template long std::__cxx11::collate< _CharT >::hash (const _CharT * __lo, const _CharT * __hi) const [inline] 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::__cxx11::collate< _CharT >::transform (const _CharT * __lo, const _CharT * __hi) const [inline] 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] Numpunct facet id.
