Detailed Description

Base class for transformation models.

Implements the identity (no transformation). Parameters and data are ignored.

Note that this class and its derived classes do not allow copying/assignment, due to the need for internal memory management associated with some of the transformation models.

Member Typedef Documentation

◆ DataPoints

typedef std::vector<DataPoint> DataPoints

Vector of coordinate pairs.

Constructor & Destructor Documentation

◆ TransformationModel() [1/3]

TransformationModel ( )
inline

Constructor.

◆ TransformationModel() [2/3]

Alternative constructor (derived classes should implement this one!) Both data and params must be provided, since some derived classes require both to create a model!

◆ ~TransformationModel()

virtual ~TransformationModel ( )
virtual

Destructor.

◆ TransformationModel() [3/3]

do not allow copy

Member Function Documentation

◆ checkDatumRange()

double checkDatumRange ( const double &  datum,
const double &  datum_min,
const double &  datum_max 
)

Check that the datum is within the valid min and max bounds.

The method checks if the datum is within the user specified min and max bounds. If the datum is below the min bounds, the min bound is returned. If the datum is above the max bounds, the max bound is returned.

◆ checkValidWeight()

bool checkValidWeight ( const String weight,
const std::vector< String > &  valid_weights 
) const

Check for a valid weighting function string.

◆ evaluate()

virtual double evaluate ( double  value) const
virtual

◆ getDefaultParameters()

static void getDefaultParameters ( Param params)
static

Gets the default parameters.

◆ getParameters()

const Param& getParameters ( ) const

Gets the (actual) parameters.

◆ getValidXWeights()

std::vector<String> getValidXWeights ( ) const

Returns a list of valid x weight function strings.

◆ getValidYWeights()

std::vector<String> getValidYWeights ( ) const

Returns a list of valid y weight function strings.

◆ operator=()

const TransformationModel& operator= ( const TransformationModel )
private

do not allow assignment

◆ unWeightData()

virtual void unWeightData ( DataPoints data)
virtual

Unweight the data by the given weight function.

◆ unWeightDatum()

double unWeightDatum ( const double &  datum,
const String weight 
) const

Apply the reverse of the weighting function to the data.

◆ weightData()

virtual void weightData ( DataPoints data)
virtual

Weight the data by the given weight function.

Currently supported valid weighting functions include the following:

  • 1 / x.
  • 1 / x2.
  • 1 / y.
  • 1 / y2.
  • ln x.
  • ln y. Note that the user needs to ensure valid bounds for the data by setting the x_datum_min/x_datum_max and y_datum_min/y_datum_max params.

◆ weightDatum()

double weightDatum ( const double &  datum,
const String weight 
) const

Weight the data according to the weighting function.
