void
parse(
t_ITER* start,
t_ITER end,
bool needInitialDot);Description
Parse the string in the random‐access‐iterator range specified by start and end to extract either a hard‐coded integer or a nested argument specification. If the specified needInitialDot is true the string is only parsed if *start == '.' and a format_error exception is thrown if the string following the initial dot is empty. If an error occurs throw an exception of type format_error, otherwise update the output start iterator to point to the first unparsed character of the string and store the parsed result into this object.
