int 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 2552 of file locale_facets.h.
int do_compare (const _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.

long do_hash (const _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.
Definition at line 2449 of file locale_facets.tcc.
collate< _CharT >::string_type 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.

long 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 2585 of file locale_facets.h.
string_type 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.
