Interface MathTransform1D

All Superinterfaces:
MathTransform
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
Departure from OGC/ISO abstract specification:
Addition of element not in the ISO/OGC specification This interface is not part of the OGC specification. It has been added as a complement of MathTransform2D and because the 1D case provides opportunities for optimization through a transform method accepting a single double primitive type.

  • 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.
