All Implemented Interfaces:

CoordinateTransformationOperator, Operator

Direct Known Subclasses:

ProjectiveOperator

public abstract class AbstractCoordinateTransformationOperator
extends Object
implements CoordinateTransformationOperator

A skeletal implementation of the CoordinateTransformationOperator interface to minimize the effort required to implement this interface. Namely, this class contain complete implementation of CoordinateTransformationOperator.apply(net.algart.math.functions.Func) method.

Method Details

map

public abstract void map(double[] destPoint,
 double[] srcPoint)

Description copied from interface: CoordinateTransformationOperator

Transforms the coordinates srcPoint of the original point in n-dimensional space to the coordinates destPoint of the destination point. Usually destPoint.length must be equal to srcPoint.length (the number of dimensions), but this requirement is not strict.

This method must not modify srcPoint array.

Warning: this method will probably not work correctly if destPoint and srcPoint is the same Java array!

Specified by:

map in interface CoordinateTransformationOperator

Parameters:

destPoint - the coordinates of the destinated point y, filled by this method.

srcPoint - the coordinates of the source point x.

apply

public Func apply(Func f)

Description copied from interface: CoordinateTransformationOperator

In this interface, this method is equivalent to CoordinateTransformedFunc.getInstance(f, this).

Specified by:

apply in interface CoordinateTransformationOperator

Specified by:

apply in interface Operator

Parameters:

f - the parent function, the arguments of which will be mapped by this operator.

Returns:

new transformed function.
