Class RubiksStickerCube

java.lang.Object
  ch.randelshofer.rubik.RubiksStickerCube

public class RubiksStickerCube
extends java.lang.Object

The RubiksStickerCube represents a Rubik's Cube by the markings of its 54 individual stickers. The RubiksStickerCube can then be asked to validate the cube to determine if it is in a legal, and thus solvable, configuration.

The stickers are expressed by the values 0 through 6 representing the six faces of the cube: front, right, down, back, left, up. The value -1 is used to express an unknown sticker value. The RubiksStickerCube can fill in values for unknown stickers.

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