Util::Lng Class Reference

Detailed Description

Wrapper for a long int, for formatted ostream output.

An Lng object has a long int numerical value, and a minimum output field width. The << operator for an Lng uses the specified width. The numerical value and width may both be optionally specified as parameters to a constructor. If the width is not specified, it is is is set to a default value equal to Format::defaultWidth().

An Lng object may be passed to an ostream as a temporary object. For example, the expression:

std::cout << Lng(13) << Lng(25, 10) << std::endl;

outputs the number 13 using the default width, followed by the number 25 in a field of minimum width 10.
