Class TwoTwoIslandMove

java.lang.Object

cusack.hcg.games.pebble.algorithms.islands.TwoTwoIslandMove

All Implemented Interfaces:

Move, MoveIterator, java.util.Iterator<Move>

public class TwoTwoIslandMove
extends java.lang.Object
implements MoveIterator, Move

The Class TwoTwoIslandMove, emulates the double pebble ability of <2,2>-islands. Simply put this class is an iterator that iterates on calls to next through all two vertex combinations in dests and attempts to move one pebble to each of these target vertices when TwoTwoIslandMove#executeMoveOnGraph(PebbleGraphController) is called. This class uses the double path finding of controllers.D2AlgorithmController#getDoublePebblePaths(Island, PebbledVertex, PebbledVertex) to perform the double pebble moves.

executeMoveOnGraph in interface Move

Parameters:

c - the c

Returns:

the number of moves made

Throws:

CouldNotCompleteMove - the move could not be made
