MathTransform1D (Geotools modules 32-SNAPSHOT API)

All Superinterfaces:

MathTransform

All Known Implementing Classes:

ExponentialTransform1D, LinearTransform1D, LogarithmicTransform1D
```
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:

GeoAPI 1.0

- Method Detail
  - 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 can't 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 can't 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 can't be inversed.
