Class MathTransformProxy

java.lang.Object
  org.geotools.referencing.operation.transform.MathTransformProxy

All Implemented Interfaces:

org.opengis.referencing.operation.MathTransform, java.io.Serializable

Direct Known Subclasses:

MathTransformProvider.Delegate

public class MathTransformProxy

extends java.lang.Object

implements org.opengis.referencing.operation.MathTransform, java.io.Serializable

A math transform which delegates part of its work to an other math transform. This is used as a starting point for subclass wanting to modifies only some aspect of an existing math transform, or to attach additional informations to it. The default implementation delegates all method calls to the underlying transform. Subclasses typically override some of those methods.

This class is serializable if the underlying transform is serializable too.
