Util::Int Class Reference

Detailed Description

Wrapper for an int, for formatted ostream output.

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

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

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

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