DESCRIPTION

An interval which can be used to represent a range of values. Intervals can be unioned and intesected. They also have the common math operation defined on them.

RiInterval();

Constructs an empty interval (max < min)

    RiInterval();

RiInterval(RiReal val);

 Constructs an interval with zero width

    RiInterval(RiReal val);

RiInterval(RiReal min, RiReal max);

 Constructs an interval. If min>max then the interval is empty.

    RiInterval(RiReal min, RiReal max);

RiReal Min() const;

    RiReal Min()      const;

RiReal Max() const;

    RiReal Max()      const;

bool IsEmpty() const;

 Returns true if interval is empty (min > max)

    bool   IsEmpty()  const;

RiReal Width() const;

 Size of the interval

    RiReal Width()    const;

RiReal Center() const;

 Center of the interval

    RiReal Center()   const;

bool In(RiReal) const;

 Returns true if value is in the interval

    bool   In(RiReal) const;

const RiInterval &operator&=(const RiInterval &);

    const  RiInterval &operator&=(const RiInterval &);

const RiInterval &operator|=(const RiInterval &);

    const  RiInterval &operator|=(const RiInterval &);

const RiInterval &operator+=(const RiInterval &);

    const RiInterval &operator+=(const RiInterval &);

const RiInterval &operator-=(const RiInterval &);

    const RiInterval &operator-=(const RiInterval &);

const RiInterval &operator*=(const RiInterval &);

    const RiInterval &operator*=(const RiInterval &);

const RiInterval &operator/=(RiReal f);

    const RiInterval &operator/=(RiReal f);

RiInterval operator-() const;

    RiInterval        operator-() const;
