    public interface InnerScoreDirector

Method Summary
`void` | `assertExpectedWorkingScore(Score expectedWorkingScore, Object completedAction)` Asserts that if the `Score` is calculated for the current `workingSolution` in the current `ScoreDirector` (with possibly incremental calculation residue), it is equal to the parameter `expectedWorkingScore`.
`void` | `assertWorkingScoreFromScratch(Score workingScore, Object completedAction)` Asserts that if the `Score` is calculated for the current `workingSolution` in a fresh `ScoreDirector` (with no incremental calculation residue), it is equal to the parameter `workingScore`.
`ScoreDirector` | `clone()` Clones this `ScoreDirector` and its `workingSolution`.
`Solution` | `cloneWorkingSolution()`
`int` | `countWorkingSolutionUninitializedVariables()`
`long` | `getCalculateCount()`
`ScoreDefinition` | `getScoreDefinition()`

`boolean` | `isWorkingEntityListDirty(long expectedWorkingEntityListRevision)`

Method Detail

### getWorkingEntityListRevision

    long getWorkingEntityListRevision()

  Returns:
    used to check `isWorkingEntityListDirty(long)` later on

### isWorkingEntityListDirty

    boolean isWorkingEntityListDirty(long expectedWorkingEntityListRevision)

  Parameters:
    `expectedWorkingEntityListRevision` - an
  Returns:
    true if the entityList might have a different set of instances now

### getScoreDirectorFactory

    InnerScoreDirectorFactory getScoreDirectorFactory()

  Returns:
    never null

### getSolutionDescriptor

    SolutionDescriptor getSolutionDescriptor()

  Returns:
    never null

### getScoreDefinition

    ScoreDefinition getScoreDefinition()

  Returns:
    never null

### cloneWorkingSolution

    Solution cloneWorkingSolution()

### getWorkingEntityCount

    int getWorkingEntityCount()

  Returns:
    >= 0

### getWorkingEntityList

    List<Object> getWorkingEntityList()

  Returns:
    never null: an empty list if there are none

### getWorkingValueCount

    int getWorkingValueCount()

  Returns:
    >= 0

### countWorkingSolutionUninitializedVariables

    int countWorkingSolutionUninitializedVariables()

### isWorkingSolutionInitialized

    boolean isWorkingSolutionInitialized()

  Returns:
    true if the `workingSolution` is initialized

### getCalculateCount

    long getCalculateCount()

  Returns:
    at least 0L

### clone

    ScoreDirector clone()

  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.

  Returns:
    never null

### getTrailingEntity

    Object getTrailingEntity(GenuineVariableDescriptor chainedVariableDescriptor,
                             Object planningValue)

  Parameters:
    `chainedVariableDescriptor` - never null, must be `GenuineVariableDescriptor.isChained()` true and known to the `SolutionDescriptor`
    `planningValue` - sometimes null
  Returns:
    never null

### setAllChangesWillBeUndoneBeforeStepEnds

    void setAllChangesWillBeUndoneBeforeStepEnds(boolean allChangesWillBeUndoneBeforeStepEnds)

  Do not waste performance by propagating changes to step (or higher) mechanisms.

  Parameters:
    `allChangesWillBeUndoneBeforeStepEnds` - true if all changes will be undone

### assertExpectedWorkingScore

    void assertExpectedWorkingScore(Score expectedWorkingScore,
                                    Object completedAction)

  Asserts that if the `Score` is calculated for the current `workingSolution` in the current `ScoreDirector` (with possibly incremental calculation residue), it is equal to the parameter `expectedWorkingScore`.

  Used to assert that skipping `ScoreDirector.calculateScore()` (when the score is otherwise determined) is correct,

  Parameters:
    `expectedWorkingScore` - never null
    `completedAction` - sometimes null, when assertion fails then the completedAction's `Object.toString()` is included in the exception message

### assertWorkingScoreFromScratch

    void assertWorkingScoreFromScratch(Score workingScore,
                                       Object completedAction)

  Asserts that if the `Score` is calculated for the current `workingSolution` in a fresh `ScoreDirector` (with no incremental calculation residue), it is equal to the parameter `workingScore`.

  Furthermore, if the assert fails, a score corruption analysis might be included in the exception message.

  Parameters:
    `workingScore` - never null
    `completedAction` - sometimes null, when assertion fails then the completedAction's `Object.toString()` is included* in the exception message
