Interface IncrementalScoreCalculator<Solution_,​Score_ extends Score<Score_>>

  • Type Parameters:
    Solution_ - the solution type, the class with the PlanningSolution annotation
    Score_ - the score type to go with the solution
    All Known Subinterfaces:
    ConstraintMatchAwareIncrementalScoreCalculator<Solution_,​Score_>

    public interface IncrementalScoreCalculator<Solution_,​Score_ extends Score<Score_>>
    Used for incremental java Score calculation. This is much faster than EasyScoreCalculator but requires much more code to implement too.

    Any implementation is naturally stateful.

      • calculateScore

        Score_ calculateScore()
        This method is only called if the Score cannot be predicted. The Score can be predicted for example after an undo Move.
        Returns:
        never null
