Class IslandMove

java.lang.Object

cusack.hcg.games.pebble.algorithms.islands.IslandMove

All Implemented Interfaces:

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

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

The Class IslandMove stores all of the possible moves from an island to the destinations taken as input in the constructor. This class does path finding as found in controllers.D2AlgorithmController to find a path for pebbles to travel from the island to the current target vertex (if possible). Successive calls to next() simply move the current target to the next target in the set of destinations past in the constructor. Calling IslandMove#executeMoveOnGraph(PebbleGraphController) attempts to move a pebble from island to the current target.
