- 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.
- Definition at line 667 of file locale_classes.h.

- _CharT * __lo1, const _CharT * __hi1, const _CharT * __lo2, const _CharT * __hi2) const [inline, 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.

- _CharT * __lo, const _CharT * __hi) const [inline, 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.

- _CharT >::do_transform (const _CharT * __lo, const _CharT * __hi) const [inline, 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.

- __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.

- 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.
