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:
__hi1 End of string 1.
__lo2 Start of string 2.
__hi2 End of string 2.
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:
__hi1 End of string 1.
__lo2 Start of string 2.
__hi2 End of string 2.
Returns:

Referenced by std::use_facet().
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:
__hi End of string.
Returns:
Definition at line 256 of file locale_classes.tcc.
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:
__hi End.
Returns:

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:
__hi End of string.
Returns:
Definition at line 724 of file locale_classes.h.
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:
__hi End of string.
Returns:
