Class PossibleActions

java.lang.Object
  rails.game.action.PossibleActions

public class PossibleActions
extends java.lang.Object

This class manages the actions that the current user can execute at any point in time. Each possible action is represented by an instance of a subclass of PossibleAction. The complete set is stored in aan ArrayList.

This class is implemented as a singleton to prevent multiple instances lingering around, as there can only be one set of possible actions at any point in time.
