Package ai.timefold.solver.constraint.streams.bavet

Class BavetConstraintStreamScoreDirector<Solution_,Score_ extends Score<Score_>>

java.lang.Object

ai.timefold.solver.core.impl.score.director.AbstractScoreDirector<Solution_,Score_,BavetConstraintStreamScoreDirectorFactory<Solution_,Score_>>

ai.timefold.solver.constraint.streams.bavet.BavetConstraintStreamScoreDirector<Solution_,Score_>

Type Parameters:

Solution_ - the solution type, the class with the PlanningSolution annotation

All Implemented Interfaces:

ScoreDirector<Solution_>, InnerScoreDirector<Solution_,Score_>, AutoCloseable, Cloneable

public final class BavetConstraintStreamScoreDirector<Solution_,Score_ extends Score<Score_>>
extends 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.
