- The
workingSolution
must never be the same instance as the bestSolution
,
it should be a (un)changed clone.
- Specified by:

in class AbstractScoreDirector<DroolsScoreDirectorFactory>
- Parameters:
workingSolution
- never null

public void afterAllVariablesChanged(Object entity)
- Specified by:
afterAllVariablesChanged
in interface ScoreDirector
- Overrides:

afterProblemFactChanged
public void afterProblemFactChanged(Object problemFact)
- Specified by:
afterProblemFactChanged
in interface ScoreDirector
- Overrides:

in class AbstractScoreDirector<DroolsScoreDirectorFactory>
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
clone
public AbstractScoreDirector clone()
- Description copied from interface:
ScoreDirector
- Clones this
ScoreDirector
and its workingSolution
.
Use ScoreDirector.getWorkingSolution()
to retrieve the workingSolution
of that clone.
This is heavy method, because it usually breaks incremental score calculation. Use it sparingly.
Therefore it's best to clone lazily by delaying the clone call as long as possible.
- Specified by:
clone
in interface ScoreDirector
- Overrides:
clone
in class AbstractScoreDirector<DroolsScoreDirectorFactory>
- Returns:
- never null
buildScoreCorruptionAnalysis
protected String buildScoreCorruptionAnalysis(ScoreDirector uncorruptedScoreDirector)
- Overrides:
buildScoreCorruptionAnalysis
in class AbstractScoreDirector<DroolsScoreDirectorFactory>
dispose
public void dispose()
- Description copied from interface:
ScoreDirector
- Needs to be called after use because some implementations needs to clean up their resources.
- Specified by:
dispose
in interface ScoreDirector
- Overrides:
dispose
in class AbstractScoreDirector<DroolsScoreDirectorFactory>
