    public abstract class AbstractScoreDirector<F extends AbstractScoreDirectorFactory>

extends Object
implements ScoreDirector, Cloneable

Abstract superclass for `ScoreDirector`.

Method Detail

### getScoreDirectorFactory

    public F getScoreDirectorFactory()

  Specified by:
    `getScoreDirectorFactory` in interface `ScoreDirector`
  Returns:
    never null

### getSolutionDescriptor

    public SolutionDescriptor getSolutionDescriptor()

### getWorkingSolution

    public Solution getWorkingSolution()

  Description copied from interface: `ScoreDirector`
  The `Solution` that is used to calculate the `Score`.

  Because a `Score` is best calculated incrementally (by delta's), the `ScoreDirector` needs to be notified when it's `workingSolution` changes.

  If the `Solution` has been changed since `ScoreDirector.calculateScore()` has been called, the `Solution.getScore()` of this `Solution` won't be correct.

  Specified by:
    `getWorkingSolution` in interface `ScoreDirector`
  Returns:
    never null

### getCalculateCount

    public long getCalculateCount()

  Specified by:
    `getCalculateCount` in interface `ScoreDirector`
  Returns:
    at least 0L

### 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.

    `setWorkingSolution` in interface `ScoreDirector`
  Parameters:
    `workingSolution` - never null

### cloneWorkingSolution

    public Solution cloneWorkingSolution()

    >= 0

### getWorkingEntityList

    public List<Object> getWorkingEntityList()

  Specified by:
    `getWorkingEntityList` in interface `ScoreDirector`
  Returns:
    never null: an empty list if there are none

### getWorkingValueCount

    public int getWorkingValueCount()

  Specified by:
    `getWorkingValueCount` in interface `ScoreDirector`
  Returns:
    >= 0

### countWorkingSolutionUninitializedVariables

    public int countWorkingSolutionUninitializedVariables()

  Specified by:
    `countWorkingSolutionUninitializedVariables` in interface `ScoreDirector`

### isWorkingSolutionInitialized

    public boolean isWorkingSolutionInitialized()

  Specified by:
    `isWorkingSolutionInitialized` in interface `ScoreDirector`
  Returns:
    true if the `workingSolution` is initialized

### setCalculatedScore

### isConstraintMatchEnabled

    public boolean isConstraintMatchEnabled()

  Specified by:
    `isConstraintMatchEnabled` in interface `ScoreDirector`
  Returns:
    true if `ScoreDirector.getConstraintMatchTotals()` can be called

### getConstraintMatchTotals

    public Collection<ConstraintMatchTotal> getConstraintMatchTotals()

  Specified by:
    `getConstraintMatchTotals` in interface `ScoreDirector`
  Returns:
    never null

### 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 `Object`
  Returns:
    never null

### dispose

    public void dispose()

  Specified by:
    `dispose` in interface `ScoreDirector`

                                    Object planningValue)

  Specified by:
    `getTrailingEntity` in interface `ScoreDirector`
  Parameters:
