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.
