Package org.optaplanner.constraint.streams.bavet

Class BavetConstraintStreamScoreDirector<Solution_,​Score_ extends org.optaplanner.core.api.score.Score<Score_>>

  • Type Parameters:
    Solution_ - the solution type, the class with the PlanningSolution annotation
    All Implemented Interfaces:
    AutoCloseable, Cloneable, org.optaplanner.core.api.score.director.ScoreDirector<Solution_>, org.optaplanner.core.impl.score.director.InnerScoreDirector<Solution_,​Score_>
    public final class BavetConstraintStreamScoreDirector<Solution_,​Score_ extends org.optaplanner.core.api.score.Score<Score_>>
extends org.optaplanner.core.impl.score.director.AbstractScoreDirector<Solution_,​Score_,​BavetConstraintStreamScoreDirectorFactory<Solution_,​Score_>>
    FP streams implementation of ScoreDirector, which only recalculates the Score of the part of the working solution that changed, instead of the going through the entire PlanningSolution. This is incremental calculation, which is fast.
