List of all members.

Public Member Functions

• override double applyFunctor (double x) const

  Implementation of the functor operation, calls map_01_to_minmax()
  

• double bias () const

  Alias for minimum.
  

• void expand (double d)

  Expand the current range to contain the given value.
  

• void expand (const Range &R)

  Expand the current range by the other range.
  

• double inv_bias () const
• double inv_scale () const
• bool invalid () const

  Return info if the range is valid, i.e. has positive range.
  

• bool isIdentity () const

  Check if this range is from 0.0 to 1.0, which would be the identity map.
  

• double map_01_to_minmax (double d) const

  Map a value in the range [0,1] to the range [min,max].
  

• double map_minmax_to_01 (double d) const

  Map value in the range [min,max] to the range [0,1].
  

• double Max () const

  maximum value
  

• double & Max ()

  modifyable maximum value
  

• double Min () const

  minimum value
  

• double & Min ()

  modifyable minimum value
  

• double offset () const

  Alias for minimum.
  

• double operator() (double x) const

  Implementation of the functor operation, which is just the value mapping into the range interval, ie. [0,1] --> [min,max].
  

• Range operator~ () const

  Compute the inverse range mapping.
  

• Range (double theMin=0.0, double theMax=1.0)

  Constructor, specify min and max.
  

• Range (double scale, double offset, bool)

  Construct a range from scale and offset.
  

• Range (const Range &R)

  Copy constructor.
  

• Range (const Range &R, bool)

  Computational constructor constructing the inverse range mapping.
  

• double scale () const

  Range interval length (max-min)
  

• void setInverse (const Range &R)
• void setRange (const Range &R)

  copies values
  

• void setScaleOffset (double scale, double offset)

  Set range to [offset, offset+scale].
  

Static Public Attributes

• static bool TypenameInitialized = InitRangeTypename()

Detailed Description

A range of double values, to be used to map certain values from one range to another.

Mapping formula is

     y = x*scale() + offset();
