Interface MathTransform1D

All Superinterfaces:

Math­Transform

All Known Implementing Classes:

Abstract­Math­Transform1D, Abstract­Math­Transform1D.Inverse

public interface MathTransform1D
extends MathTransform

Transforms one-dimensional coordinate points. Coordinate­Operation.get­Math­Transform() may returns instance of this interface when source and destination coordinate systems are both one dimensional. Math­Transform1D extends Math­Transform by adding a simple method transforming a value without the overhead of creating data array.

Since:

1.0

Method Details

transform

double transform(double value)
          throws TransformException

Transforms the specified value.

Parameters:

value - The value to transform.

Returns:

the transformed value.

Throws:

Transform­Exception - if the value cannot be transformed.

derivative

double derivative(double value)
           throws TransformException

Gets the derivative of this function at a value. The derivative is the 1×1 matrix of the non-translating portion of the approximate affine map at the value.

Parameters:

value - The value where to evaluate the derivative.

Returns:

The derivative at the specified point.

Throws:

Transform­Exception - if the derivative cannot be evaluated at the specified point.

inverse

MathTransform1D inverse()
                 throws NoninvertibleTransformException

Creates the inverse transform of this object.

Specified by:

inverse in interface Math­Transform

Returns:

The inverse transform.

Throws:

Noninvertible­Transform­Exception - if the transform cannot be inverted.
