public final class UniscaledReduction

extends java.lang.Object

implements Reduction

The implementation of an abstract space reduction based on affine transform y=scale*(x-origin) with the same scale factor for all directions. Here x is an initial point, y is the reduced point, scale is a scale factor, origin is an origin point.
