Test char_type classification. This function finds a mask M for c and compares it to mask m.
do_is() is a hook for a derived facet to change the behavior of classifying. do_is() must always return the same result for the same input.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Return a mask array. This function finds the mask for each char_type in the range [lo,hi) and successively writes it to vec. vec must have as many elements as the input.
do_is() is a hook for a derived facet to change the behavior of classifying. do_is() must always return the same result for the same input.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Narrow char_type to char. This virtual function converts the argument to char using the simplest reasonable transformation. If the conversion fails, dfault is returned instead.
do_narrow() is a hook for a derived facet to change the behavior of narrowing. do_narrow() must always return the same result for the same input.
Note: this is not what you want for codepage conversions. See codecvt for that.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Referenced by std::ctype< char >::narrow().
Narrow char_type array to char. This virtual function converts each char_type in the range [__lo,__hi) to char using the simplest reasonable transformation and writes the results to the destination array. For any element in the input that cannot be converted, __dfault is used instead.
do_narrow() is a hook for a derived facet to change the behavior of narrowing. do_narrow() must always return the same result for the same input.
Note: this is not what you want for codepage conversions. See codecvt for that.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Find char_type matching mask. This function searches for and returns the first char_type c in [__lo,__hi) for which is(__m,c) is true.
do_scan_is() is a hook for a derived facet to change the behavior of match searching. do_is() must always return the same result for the same input.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Find char_type not matching mask. This function searches for and returns a pointer to the first char_type c of [lo,hi) for which is(m,c) is false.
do_scan_is() is a hook for a derived facet to change the behavior of match searching. do_is() must always return the same result for the same input.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Convert to lowercase. This virtual function converts the argument to lowercase if possible. If not possible (for example, '2'), returns the argument.
do_tolower() is a hook for a derived facet to change the behavior of lowercasing. do_tolower() must always return the same result for the same input.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Referenced by std::ctype< char >::tolower().
Convert array to lowercase. This virtual function converts each char_type in the range [__lo,__hi) to lowercase if possible. Other elements remain untouched.
do_tolower() is a hook for a derived facet to change the behavior of lowercasing. do_tolower() must always return the same result for the same input.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Convert to uppercase. This virtual function converts the char_type argument to uppercase if possible. If not possible (for example, '2'), returns the argument.
do_toupper() is a hook for a derived facet to change the behavior of uppercasing. do_toupper() must always return the same result for the same input.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Referenced by std::ctype< char >::toupper().
Convert array to uppercase. This virtual function converts each char_type in the range [__lo,__hi) to uppercase if possible. Other elements remain untouched.
do_toupper() is a hook for a derived facet to change the behavior of uppercasing. do_toupper() must always return the same result for the same input.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Widen char. This virtual function converts the char to char_type using the simplest reasonable transformation.
do_widen() is a hook for a derived facet to change the behavior of widening. do_widen() must always return the same result for the same input.
Note: this is not what you want for codepage conversions. See codecvt for that.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Referenced by std::ctype< char >::widen().
Widen char array. This function converts each char in the input to char_type using the simplest reasonable transformation.
do_widen() is a hook for a derived facet to change the behavior of widening. do_widen() must always return the same result for the same input.
Note: this is not what you want for codepage conversions. See codecvt for that.
Parameters:
Returns:
Implements std::__ctype_abstract_base< _CharT >.
Test char_type classification. This function finds a mask M for __c and compares it to mask __m. It does so by returning the value of ctype<char_type>::do_is().
Parameters:
