Detailed Description

This class is used to perform formatting on integer passed to the Output class.

It is rarely used as-is but with some inlines functions performing formatting: io::base, io::bin, io::hex, op::width, io::align, io::left, io::center, io::right, io::pad, io::uppercase, io::lowercase.

Member Data Documentation

unsigned elm::io::IntFormat::_align

Alignment of integer in the field. One of LEFT, CENTER or RIGHT.

Referenced by align(), center(), left(), elm::io::Output::print(), and right().

IntFormat elm::io::IntFormat::_base

Numeric base used to display the integer (default to 10).

Referenced by base(), bin(), dec(), hex(), oct(), and elm::io::Output::print().

char elm::io::IntFormat::_displaySign

If true, the sign of signed value is always displayed. Else only the minus is displayed when needed.

Referenced by elm::io::Output::print(), and sign().

char elm::io::IntFormat::_pad

Character used to pad the displayed integer in the field (default '0').

Referenced by pad(), and elm::io::Output::print().

unsigned elm::io::IntFormat::_sign

If true, ever display the sign. If false (default), only display negative sign.

Referenced by bin(), hex(), oct(), and elm::io::Output::print().

char elm::io::IntFormat::_size

Referenced by elm::io::Output::print().

unsigned elm::io::IntFormat::_upper

If true, upper case characters will be used to display integer whose base is greater than 10. If false (default), lower case characters will be used.

t::int64 elm::io::IntFormat::_val

Referenced by operator()(), and elm::io::Output::print().

unsigned char elm::io::IntFormat::_width
