Constructor Detail

LoadMemorizeCoordinate

public LoadMemorizeCoordinate(int index)

Creates a new CoordinateOperation removing the last double value from a coordinate array and loading it at the specified index in the array.

Parameters:

index - final dimension of the new coordinate

Method Detail

getIndexSaved

public int getIndexSaved()

transform

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

Load the last memorized coordinates : remove the last ordinate of the array, and load it at index indexSaved.

Specified by:

transform in interface CoordinateOperation

Specified by:

transform in class AbstractCoordinateOperation

Parameters:

coord - is an array containing four ordinates or more

Returns:

Throws:

IllegalCoordinateException - if coord is not compatible with this CoordinateOperation.
