Class XAffineTransform

java.lang.Object

      org.deegree.model.csct.resources.XAffineTransform

All Implemented Interfaces:

Serializable, Cloneable

Direct Known Subclasses:

AffineTransform2D

public abstract class XAffineTransform
extends AffineTransform

Utility methods for affine transforms. This class provides a set of public static methods working on any AffineTransform.

Class XAffineTransform overrides all mutable methods of AffineTransform in order to check for permission before to change the transform's state. If checkPermission() is defined to always thrown an exception, then XAffineTransform is immutable.
