Class Move

java.lang.Object
  cs1705.tetris.Move

public class Move

extends Object

This class represents a single move made by or considered by a Tetris "Brain" class. A move can have a "score" associated with it. This score can be used by a Brain class to reflect the relative value of this move in comparison with alternatives, where higher scores are associated with less valuable moves (think "higher score" means "higher buildup of bricks").
