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:
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<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.
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<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:
lo Start of string.
hi End of string.
Returns: Hash value.

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:
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<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:
lo Start of string.
hi End of string.
Returns: Hash value.
Definition at line 2556 of file locale_facets.h.
References std::collate< CharT >::do_hash().
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:
lo Start of string.
hi End of string.
Returns: Transformed string_type.
