Class FaceletCube

java.lang.Object
  ch.randelshofer.rubik.solver.FaceletCube

public class FaceletCube
extends java.lang.Object

The FaceletCube represents the cube by the markings of the 54 individual facelets. The FaceletCube can then be asked to validate the cube to determine if it is in a legal, and thus solvable, configuration.

This class has been derived from facecube.cpp and facecube.h from the 'Kociemba Cube Solver 1.0' (KCube) (c) Greg Schmidt.
