template<class OutputIter> OutputIter format( OutputIter out, const char_type* fmt_first, const char_type* fmt_last, regex_constants::match_flag_type flags = regex_constants::format_default) const;
Preconditions: ready() == true and OutputIter meets the requirements for aCpp17OutputIterator ([output.iterators]).
Effects: Copies the character sequence [fmt_first, fmt_last) to OutputIter out.
Replaces each format specifier or escape sequence in the copied range with either the character(s) it represents or the sequence of characters within *this to which it refers.
The bitmasks specified in flags determine which format specifiers and escape sequences are recognized.
Returns: out.
template<class OutputIter, class ST, class SA> OutputIter format( OutputIter out, const basic_string<char_type, ST, SA>& fmt, regex_constants::match_flag_type flags = regex_constants::format_default) const;
Effects: Equivalent to:return format(out, fmt.data(), fmt.data() + fmt.size(), flags);
template<class ST, class SA> basic_string<char_type, ST, SA> format( const basic_string<char_type, ST, SA>& fmt, regex_constants::match_flag_type flags = regex_constants::format_default) const;
Preconditions: ready() == true.
Effects: Constructs an empty string result of type basic_string<char_type, ST, SA> and calls:format(back_inserter(result), fmt, flags);
Returns: result.
string_type format( const char_type* fmt, regex_constants::match_flag_type flags = regex_constants::format_default) const;
Preconditions: ready() == true.
Effects: Constructs an empty string result of type string_type and calls:format(back_inserter(result), fmt, fmt + char_traits<char_type>::length(fmt), flags);
Returns: result.
