Functions

template<typename T, bool INCLUDE_UPPER = true>
Range<T, INCLUDE_UPPER> MakeRange(T _l, T _u)

Build a new range with auto-detected type.

template<bool INCLUDE_UPPER = true>
inline Range<int, INCLUDE_UPPER> IntRange(int _l, int _u)

Build a new range of type int.

template<bool INCLUDE_UPPER = true>
inline Range<double, INCLUDE_UPPER> DRange(double _l, double _u)

Build a new range of type double.

template<typename T, bool INCLUDE_UPPER = true>
class Range

#include <Range.hpp>

A range of values from a lower limit to and upper limit, of any provided type.

inline T &Lower()

inline T &Upper()

inline const T &Lower() const noexcept

inline const T &Upper() const noexcept

inline bool Has(T value) const

Determine if a provided value is in the range INCLUSIVE of the endpoints.

inline bool Valid(T value) const

inline bool HasRange(this_t in_range)

inline bool IsConnected(this_t in) const

Will identify if two ranges are next to each other or overlapping.

inline bool HasOverlap(this_t in) const

Determine if there is overlap between two range. Similar to IsConnected, but cannot be merely adjacent.

inline T CalcOverlap(this_t in) const

Determine the amount of overlap between two range.

inline bool Expand(T val)

Expand this range to encompass a provided value.

Parameters:

val – Value to expand through.

Returns:

Whether the range has changed due to this expansion.

template<typename ...Ts>
inline bool Expand(T val1, T val2, Ts... args)

Expand this range to encompass all provided values.

Returns:

Whether the range has changed due to this expansion.

inline bool Merge(this_t in)

Merge this range with another. Must be adjacent or overlap (return false if not!)

inline bool Append(T val)

Add a specified value to the end of a range (or return false if failed).

inline T Clamp(T _in) const

Force a value into range.

inline T LimitValue(T _in) const

inline double ToFraction(T _in) const

inline T FromFraction(double frac) const

inline void LimitLower(T in)

inline void LimitUpper(T in)

inline size_t CalcBin(T value, size_t num_bins) const

inline vector<T> Spread(const size_t s) const

Produce a vector that spreads values evenly across the range.
