class locale::Impl

Common base for ctype facet.

This template class provides implementations of the public functions that forward to the protected virtual functions.

This template also provides abtract stubs for the protected virtual functions.

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: lo Pointer to start of range.

hi Pointer to end of range.

vec Pointer to an array of mask storage.

Returns: hi.

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: c The char_type to find the mask of.

m The mask to compare against.

Returns: (M & m) != 0.

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: lo Pointer to start of range.

hi Pointer to end of range.

dfault Char to use if conversion fails.

to Pointer to the destination array.

Returns: hi.

Implemented in std::ctype< CharT >.
