org.opengis.referencing.operation.TransformException
Common superclass for a number of transformation-related exceptions. {@code TransformException} are thrown by {@link MathTransform}when a coordinate transformation can't be {@linkplain MathTransform#inverse inverted}( {@link NoninvertibleTransformException}), when the {@linkplain MathTransform#derivative derivative} can't be computed or when a coordinatecan't be {@linkplain MathTransform#transform(DirectPosition,DirectPosition) transformed}. It is also thrown when {@link CoordinateOperationFactory} fails to find a path between two{@linkplain org.opengis.referencing.crs.CoordinateReferenceSystem coordinate reference systems}. @author Martin Desruisseaux (IRD) @since GeoAPI 1.0 @source $URL$
