Member Function Documentation

compare()

template<typename _CharT>

int std::collate< _CharT >::compare ( const _CharT *  __lo1, const _CharT *  __hi1, const _CharT *  __lo2, const _CharT *  __hi2  ) const

inlineinherited

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 700 of file locale_classes.h.

do_compare()

template<typename _CharT>

int std::collate< _CharT >::do_compare ( const _CharT *  __lo1, const _CharT *  __hi1, const _CharT *  __lo2, const _CharT *  __hi2  ) const

protectedvirtualinherited

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.

do_hash()

template<typename _CharT>

long std::collate< _CharT >::do_hash ( const _CharT *  __lo, const _CharT *  __hi  ) const

protectedvirtualinherited

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 256 of file locale_classes.tcc.

do_transform()

template<typename _CharT>

collate< _CharT >::string_type std::collate< _CharT >::do_transform ( const _CharT *  __lo, const _CharT *  __hi  ) const

protectedvirtualinherited

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.

hash()

template<typename _CharT>

long std::collate< _CharT >::hash ( const _CharT *  __lo, const _CharT *  __hi  ) const

inlineinherited

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 733 of file locale_classes.h.

transform()

template<typename _CharT>

string_type std::collate< _CharT >::transform ( const _CharT *  __lo, const _CharT *  __hi  ) const

inlineinherited

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.
