Public Functions

inline range2()

constexpr range2(const ThisType&) = default

inline explicit constexpr range2(ScalarType size)

inline constexpr void SetEmpty(): Sets the range to an empty interval.

inline constexpr range2(const MinMaxType &min, const MinMaxType &max): This constructor initializes the minimum and maximum points.

inline const MinMaxType &GetMin() const: Returns the minimum value of the range.

inline const MinMaxType &GetMax() const: Returns the maximum value of the range.

inline MinMaxType GetSize() const: Returns the size of the range.

inline MinMaxType GetMidpoint() const: Returns the midpoint of the range, that is, 0.5*(min+max). Note: this returns zero in the case of default-constructed ranges, or ranges set via SetEmpty().

inline void SetMin(const MinMaxType &min): Sets the minimum value of the range.

inline void SetMax(const MinMaxType &max): Sets the maximum value of the range.

inline bool IsEmpty() const: Returns whether the range is empty (max < min).

inline void ExtendBy(const MinMaxType &point)

Modifies the range if necessary to surround the given value.

Deprecated:: Use UnionWith() instead.

inline void ExtendBy(const ThisType &range)

Modifies the range if necessary to surround the given range.

Deprecated:: Use UnionWith() instead.

inline bool Contains(const MinMaxType &point) const: Returns true if the point is located inside the range. As with all operations of this type, the range is assumed to include its extrema.

inline bool Contains(const ThisType &range) const: Returns true if the range is located entirely inside the range. As with all operations of this type, the ranges are assumed to include their extrema.

inline bool IsInside(const MinMaxType &point) const

Returns true if the point is located inside the range. As with all operations of this type, the range is assumed to include its extrema.

Deprecated:: Use Contains() instead.

inline bool IsInside(const ThisType &range) const

Returns true if the range is located entirely inside the range. As with all operations of this type, the ranges are assumed to include their extrema.

Deprecated:: Use Contains() instead.

inline bool IsOutside(const ThisType &range) const: Returns true if the range is located entirely outside the range. As with all operations of this type, the ranges are assumed to include their extrema.

inline const ThisType &UnionWith(const ThisType &b): Extend this to include b.

inline const ThisType &UnionWith(const MinMaxType &b): Extend this to include b.

inline const ThisType &Union(const ThisType &b)

Extend this to include b.

Deprecated:: Use UnionWith() instead.

inline const ThisType &Union(const MinMaxType &b)

Extend this to include b.

Deprecated:: Use UnionWith() instead.

inline const ThisType &IntersectWith(const ThisType &b): Modifies this range to hold its intersection with b and returns the result.

inline const ThisType &Intersection(const ThisType &b)

Modifies this range to hold its intersection with b and returns the result.

Deprecated:: Use IntersectWith() instead.

inline ThisType &operator+=(const ThisType &b): unary sum.

inline ThisType &operator-=(const ThisType &b): unary difference.

inline ThisType &operator*=(double m): unary multiply.

inline ThisType &operator/=(double m): unary division.

inline ThisType operator+(const ThisType &b) const: binary sum.

inline ThisType operator-(const ThisType &b) const: binary difference.

inline bool operator==(const ThisType &b) const: The min and max points must match exactly for equality.

inline bool operator!=(const ThisType &b) const

inline double GetDistanceSquared(const MinMaxType &p) const: Compute the squared distance from a point to the range.

inline MinMaxType GetCorner(size_t i) const: Returns the ith corner of the range, in the following order: SW, SE, NW, NE.

inline ThisType GetQuadrant(size_t i) const: Returns the ith quadrant of the range, in the following order: SW, SE, NW, NE.
