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;
Requires: ready() == true and OutputIter shall satisfy the requirements for an Output Iterator ([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;
Requires: 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;
Requires: 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.
