Public typedefs.

template<typename _CharT > typedef basic_string<_CharT> std::collate_byname< _CharT >::string_type¶

Public typedefs.

template<typename _CharT > 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

Returns

template<typename _CharT > 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.

Parameters

Returns

References std::basic_string< _CharT, _Traits, _Alloc >::c_str(), std::basic_string< _CharT, _Traits, _Alloc >::data(), and std::basic_string< _CharT, _Traits, _Alloc >::length().

template<typename _CharT > 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

Returns

template<typename _CharT > 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

Returns

References std::basic_string< _CharT, _Traits, _Alloc >::c_str(), std::basic_string< _CharT, _Traits, _Alloc >::data(), and std::basic_string< _CharT, _Traits, _Alloc >::length().

template<typename _CharT > 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

Returns

template<typename _CharT > 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

Returns

template<typename _CharT > locale::id std::collate< _CharT >::id [static], [inherited]¶

Numpunct facet id.
