Class MoveNode

java.lang.Object
  javax.swing.tree.DefaultMutableTreeNode
      ch.randelshofer.rubik.parser.Node
          ch.randelshofer.rubik.parser.MoveNode

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, javax.swing.tree.MutableTreeNode, javax.swing.tree.TreeNode

public class MoveNode
extends Node

A MoveNode holds one rotation of one or multiple layers in a specific direction by a specific angle. The side effect of a MoveNode on a Cube is the concatenation of all permutation cycles caused by the rotation.

Version:

6.2 2012-02-08 Fixes quarter turn count for angle values > +/-3.
6.0.1 2008-01-18 Fixed face turn countTurned for 3x3 cube.
6.0 2007-06-16 Renamed from TwistNode to MoveNode.
5.0 2005-01-31 Reworked.

Method Detail

applyTo

public void applyTo(Cube cube,
                    boolean inverse)

Description copied from class: Node

Applies the symbol represented by this node to the cube.

Overrides:

applyTo in class Node

Parameters:

cube - A cube to be transformed by this symbol.

inverse - If true, the transform will be done in inverse order.

getAxis

public int getAxis()

getLayerMask

public int getLayerMask()

getAngle

public int getAngle()

setAxis

public void setAxis(int newValue)

setLayerMask

public void setLayerMask(int newValue)

setAngle

public void setAngle(int newValue)

getLayerCount

public int getLayerCount()

setLayerCount

public void setLayerCount(int newValue)

getLayerTurnCount

public int getLayerTurnCount()

Gets the layer turn countTurned of the subtree starting at this node.

Overrides:

getLayerTurnCount in class Node

getBlockTurnCount

public int getBlockTurnCount()
