template<typename _CharT> std::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<typename _CharT> std::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<typename _CharT> int std::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<typename _CharT> 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<typename _CharT> 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<typename _CharT> 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: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]¶
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<typename _CharT> string_type std::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.
