class ROOT::Fit::DataRange


   class describing the range in the coordinates
   it supports  multiple range in a coordinate.
   The rnage dimension is the dimension of the coordinate, its size is
   the number of interval for each coordinate.
   Default range is -inf, inf
   Range can be modified with the add range method

Function documentation

explicit DataRange(unsigned int dim = 1)
      Default constructor (infinite range)

{}
DataRange(double xmin, double xmax)
      construct a range for [xmin, xmax]

DataRange(double xmin, double xmax, double ymin, double ymax)
      construct a range for [xmin, xmax] , [ymin, ymax]

DataRange(double xmin, double xmax, double ymin, double ymax, double zmin, double zmax)
      construct a range for [xmin, xmax] , [ymin, ymax] , [zmin, zmax]

unsigned int NDim() const
      get range dimension

{ return fRanges.size(); }
unsigned int Size(unsigned int icoord) const
      return range size for coordinate icoord (starts from zero)
      Size == 0 indicates no range is present [-inf, + inf]

const RangeSet & Ranges(unsigned int icoord) const
       return the vector of ranges for the coordinate icoord

std::pair<double, double> operator()(unsigned int icoord) const
       return the first range for the coordinate icoord.
       Useful method when only one range is present for the given coordinate

void GetRange(unsigned int icoord, double& xmin, double& xmax) const
      get the first range for given coordinate

void GetRange(double& xmin, double& xmax) const
      get range for the x - coordinate

{ GetRange(0,xmin,xmax); }
void GetRange(double& xmin, double& xmax, double& ymin, double& ymax) const
      get range for the x and y coordinates

GetRange(unsigned int icoord, double& xmin, double& xmax) const
~DataRange()
      Destructor (no operations)

{}
void AddRange(unsigned int icoord, double xmin, double xmax)
      add a range [xmin,xmax] for the new coordinate icoord
      Adding a range does not delete existing one, but takes the OR with
      existing ranges.
      if want to replace range use method SetRange, which replace range with existing one

void AddRange(double xmin, double xmax)
      add a range [xmin,xmax] for the first coordinate icoord

{ AddRange(0,xmin,xmax); }
void AddRange(double xmin, double xmax, double ymin, double ymax)
      add a range [xmin,xmax] for the first and [ymin,ymax] for the second coordinate

{ AddRange(0,xmin,xmax); AddRange(1,ymin,ymax); }
void AddRange(double xmin, double xmax, double ymin, double ymax, double zmin, double zmax)
      add a range [xmin,xmax] for the first and [ymin,ymax] for the second coordinate and
      [zmin,zmax] for the third coordinate

void SetRange(unsigned int icoord, double xmin, double xmax)
      set a range [xmin,xmax] for the new coordinate icoord
      If more range exists for other coordinates, delete the existing one and use it the new one
      Use Add range if want to keep the union of the existing ranges

void SetRange(double xmin, double xmax)
      set a range [xmin,xmax] for the first coordinate icoord

{ SetRange(0,xmin,xmax); }
void SetRange(double xmin, double xmax, double ymin, double ymax)
      set a range [xmin,xmax] for the first and [ymin,ymax] for the second coordinate

{ SetRange(0,xmin,xmax); SetRange(1,ymin,ymax); }
void SetRange(double xmin, double xmax, double ymin, double ymax, double zmin, double zmax)
      set a range [xmin,xmax] for the first and [ymin,ymax] for the second coordinate and
      [zmin,zmax] for the third coordinate

void Clear(unsigned int icoord = 0)
      clear all ranges in one coordinate (is now -inf, +inf)

bool IsInside(double x, unsigned int icoord = 0) const
      check if a point is inside the range for the given coordinate

void CleanRangeSet(unsigned int icoord, double xmin, double xmax)
       internal function to remove all the existing ranges between xmin and xmax
       called when a new range is inserted
