template<typename _CharT > int \fBstd::collate\fP< _CharT >::compare (const _CharT *__lo1, const _CharT *__hi1, const _CharT *__lo2, const _CharT *__hi2) const\fC [inline]\fP, \fC [inherited]\fP

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 > virtual int \fBstd::collate\fP< _CharT >::do_compare (const _CharT *__lo1, const _CharT *__hi1, const _CharT *__lo2, const _CharT *__hi2) const\fC [protected]\fP, \fC [virtual]\fP, \fC [inherited]\fP

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 > virtual long \fBstd::collate\fP< _CharT >::do_hash (const _CharT *__lo, const _CharT *__hi) const\fC [protected]\fP, \fC [virtual]\fP, \fC [inherited]\fP

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 > virtual \fBstring_type\fP \fBstd::collate\fP< _CharT >::do_transform (const _CharT *__lo, const _CharT *__hi) const\fC [protected]\fP, \fC [virtual]\fP, \fC [inherited]\fP

Transform string to comparable form. This function is a hook for derived classes to change the value returned.

Parameters:

__lo Start.

__hi End.

Returns:

transformed string.

template<typename _CharT > long \fBstd::collate\fP< _CharT >::\fBhash\fP (const _CharT *__lo, const _CharT *__hi) const\fC [inline]\fP, \fC [inherited]\fP

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 > \fBstring_type\fP \fBstd::collate\fP< _CharT >::transform (const _CharT *__lo, const _CharT *__hi) const\fC [inline]\fP, \fC [inherited]\fP

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.

template<typename _CharT > \fBlocale::id\fP \fBstd::collate\fP< _CharT >::id\fC [static]\fP, \fC [inherited]\fP

Numpunct facet id.
