Class IncrementalScoreDirector
java.lang.Object
org.optaplanner.core.impl.score.director.AbstractScoreDirector<IncrementalScoreDirectorFactory>
org.optaplanner.core.impl.score.director.incremental.IncrementalScoreDirector
- All Implemented Interfaces:
- Cloneable, InnerScoreDirector, 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.

IncrementalScoreDirector
public IncrementalScoreDirector(IncrementalScoreDirectorFactory scoreDirectorFactory,
IncrementalScoreCalculator incrementalScoreCalculator)
getIncrementalScoreCalculator
public IncrementalScoreCalculator getIncrementalScoreCalculator()
setWorkingSolution
public void setWorkingSolution(Solution workingSolution)
- Description copied from interface:
ScoreDirector
- The
workingSolution must never be the same instance as the bestSolution,
it should be a (un)changed clone.
Only call this method on a separate ScoreDirector instance,
build by Solver.getScoreDirectorFactory(),
not on the one used inside the Solver itself.
- Specified by:
setWorkingSolution in interface ScoreDirector- Overrides:
setWorkingSolution in class AbstractScoreDirector<IncrementalScoreDirectorFactory>
- Parameters:
workingSolution - never null
calculateScore
public Score calculateScore()
- Description copied from interface:
ScoreDirector
- Calculates the
Score and updates the workingSolution accordingly.
- Returns:
- never null, the
Score of the workingSolution
