Member Function Documentation

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 662 of file locale_classes.h.

virtual 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.

virtual 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.

virtual 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.

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 695 of file locale_classes.h.

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.
