INTERVAL Class Reference

This class represents a closed interval object. An interval is a pair of double values [x,y], representing all values (of type double) starting from x to y. We name them the left and the right of the interval. Also, we ca associate a cost (weight) to an interval. More...

Constructor & Destructor Documentation

INTERVAL::INTERVAL ( )

Constructor of an empty interval [0,0] with a unit cost.

INTERVAL::INTERVAL	(	double	x,
		double	y
	)

Constructor with two arguments, the left and the right values of the interval.

Parameters:

	x	the left value
	y	the right value

Exceptions:

INVALID_INTERVAL

if x>y

INTERVAL::INTERVAL	(	double	x,
		double	y,
		double	w
	)

Constructor with three arguments.

Parameters:

	x	the left value
	y	the right value
	w	the weight

Exceptions:

INVALID_INTERVAL

if x>y
