Field Detail

IDENTITY

public static final Identity IDENTITY

The identity transformation. When used to transform coordinates, it returns the input coordinates.

Method Detail

transform

public double[] transform(double[] coord)
                   throws IllegalCoordinateException

Apply the identity transformation to input coordinates.

Specified by:

transform in interface CoordinateOperation

Specified by:

transform in class AbstractCoordinateOperation

Parameters:

coord - is an array containing one, two or three ordinates

Returns:

a double array containing the output coordinate

Throws:

IllegalCoordinateException

inverse

public CoordinateOperation inverse()
                            throws NonInvertibleOperationException

Creates the inverse CoordinateOperation.

Specified by:

inverse in interface CoordinateOperation

Overrides:

inverse in class AbstractCoordinateOperation

Throws:

NonInvertibleOperationException
