Class TransformAdapter

java.lang.Object
  jwo.landserf.process.TransformAdapter

All Implemented Interfaces:

Transformable

public class TransformAdapter
extends Object
implements Transformable

Provides a default transformer that leaves coordinates unchanged. This can be useful for methods that require a Transformable object where a default transformation is needed.

Constructor Summary

TransformAdapter()

Method Summary

boolean	doInterpolation() Indicates whether the transformation uses nearest neighbour (false) or some interpolator (true).
String	getDescription() Provides a description of this transformation.
Footprint	invTransformCoords(Footprint fpIn) Performs an inverse transform of the location given by the footprint, but in this case, creates a new identical footprint.
Footprint	transformCoords(Footprint fpIn) Transforms the location given by the footprint, but in this case creates a new identical footprint.

public TransformAdapter()

Method Detail

transformCoords

public Footprint transformCoords(Footprint fpIn)

Transforms the location given by the footprint, but in this case creates a new identical footprint.

Specified by:

transformCoords in interface Transformable

Parameters:

fpIn - Incoming footprint to transform.

Returns:

Transformed footprint (unchanged).

invTransformCoords

public Footprint invTransformCoords(Footprint fpIn)

Performs an inverse transform of the location given by the footprint, but in this case, creates a new identical footprint.

Specified by:

invTransformCoords in interface Transformable

Parameters:

fpIn - Incoming footprint on which to perform the inverse transform.

Returns:

Transformed footprint (unchanged).

getDescription

public String getDescription()

Provides a description of this transformation.

Specified by:

getDescription in interface Transformable

Returns:

Description of the transformation.

doInterpolation

public boolean doInterpolation()

Indicates whether the transformation uses nearest neighbour (false) or some interpolator (true). In this case, it always uses nearest neighbour.

Specified by:

doInterpolation in interface Transformable

Returns:

True if transformation should perform some local interpolation.
