Class IncrementalScoreDirector

java.lang.Object
  org.drools.planner.core.score.director.AbstractScoreDirector<IncrementalScoreDirectorFactory>
      org.drools.planner.core.score.director.incremental.IncrementalScoreDirector

All Implemented Interfaces:

ScoreDirector

public class IncrementalScoreDirector
extends AbstractScoreDirector<IncrementalScoreDirectorFactory>

Incremental java implementation of ScoreDirector, which only recalculates the Score of the part of the Solution workingSolution that changed, instead of the going through the entire Solution. This is incremental calculation, which is fast.
