A format context for use by formatter::parse() partial specialization. It provides access to iterators for the start and end of the remaining (unparsed) format string, as well as argument counters.

basic_format_parse_context [constructor] | Constructors |
advance_to | Update the held iterator to the unparsed portion of the format string to be the specified it. Subsequent calls to begin will return this value. The behavior is undefined unless it is a valid iterator to the format string used in construction of this context. |
begin | Return an iterator to the start of the unparsed portion of the format string. |
check_arg_id | Check that the specified id is a valid argument index. If the indexing mode is unset, the indexing mode is set to e_MANUAL. If the indexing mode is e_AUTOMATIC, caused by a previous call to next_arg_id then an exception of type format_error is thrown. If id is not less than the number of arguments then an exception of type format_error is thrown. |
end | Return an iterator to the start of the unparsed portion of the format string. |
next_arg_id | Return the index of the next-unused argument. If the indexing mode is unset, the indexing mode is set to e_AUTOMATIC. If the indexing mode is e_MANUAL, caused by a previous call to check_arg_id then an exception of type format_error is thrown. If there are no remaining unused arguments then an exception of type format_error is thrown. |
