/**
|
||
|
|
* The abstract class for an Abstract Game.
|
||
|
|
* All inheriting classes should be turn taking games (see method run).
|
||
|
|
*
|
||
|
|
* The abstract game knows the model of the current game state (something implementing
|
||
|
|
* an IBoard). It handles the players by providing a map from the Player class
|
||
|
|
* (an enum for the player order in the game) to the abstractGamePlayer class
|
||
|
|
* (a class that can choose a Ply from any given position).
|
||
|
|
*
|
||
|
|
* The control loop in the run method selects the appropriate player, sends him
|
||
|
|
* what should be a copy of the current game state to help him make his decision.
|
||
|
|
* If a player returns an illegal move, an exception is thrown and the game stops.
|
||
|
|
* Otherwise, when the game finishes the method returns the result.
|
||
|
|
*
|
||
|
|
* The logic of the game rule is handled in the class IBoard.
|
||
|
|
* In particular, it is possible that the turn taking does not take form of a round
|
||
|
|
* robin and switches between players in a non uniform ad hoc fashion.
|
||
|
|
*
|
||
|
|
* Potential evolution of this class could take into account clocks for the players,
|
||
|
|
* which would be better handled here than in the Abstractboard class.
