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<DroolsScoreDirectorFactory>
- Parameters:
workingSolution
- never null
getWorkingFacts
public Collection<Object> getWorkingFacts()
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
isConstraintMatchEnabled
public boolean isConstraintMatchEnabled()
- Returns:
- true if
ScoreDirector.getConstraintMatchTotals()
can be called
getConstraintMatchTotals
public Collection<ConstraintMatchTotal> getConstraintMatchTotals()
- Returns:
- never null
clone
public DroolsScoreDirector clone()
- Description copied from interface:
InnerScoreDirector
- 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 InnerScoreDirector
- Overrides:
clone
in class AbstractScoreDirector<DroolsScoreDirectorFactory>
- Returns:
- never null
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>
afterEntityAdded
public void afterEntityAdded(EntityDescriptor entityDescriptor,
Object entity)
- Overrides:
afterEntityAdded
in class AbstractScoreDirector<DroolsScoreDirectorFactory>

Object entity)
- Specified by:
afterVariableChanged
in interface ScoreDirector
- Overrides:
afterVariableChanged
in class AbstractScoreDirector<DroolsScoreDirectorFactory>
afterEntityRemoved
public void afterEntityRemoved(EntityDescriptor entityDescriptor,
Object entity)
- Overrides:
