Type Parameters:

Solution_ - the solution type, the class with the PlanningSolution annotation

Score_ - the score type to go with the solution

All Known Subinterfaces:

ConstraintMatchAwareIncrementalScoreCalculator<Solution_,Score_>
```
public interface IncrementalScoreCalculator<Solution_,Score_ extends Score<Score_>>
```
Used for incremental java Score calculation. This is much faster than EasyScoreCalculator but requires much more code to implement too.
Any implementation is naturally stateful.

- Method Detail
  - resetWorkingSolution
```
void resetWorkingSolution(Solution_ workingSolution)
```
    There are no beforeEntityAdded(Object) and afterEntityAdded(Object) calls for entities that are already present in the workingSolution.
    
    Parameters:
    
    workingSolution - never null
  - beforeEntityAdded
```
void beforeEntityAdded(Object entity)
```
    Parameters:
    
    entity - never null, an instance of a PlanningEntity class
  - afterEntityAdded
```
void afterEntityAdded(Object entity)
```
    Parameters:
    
    entity - never null, an instance of a PlanningEntity class
  - beforeVariableChanged
```
void beforeVariableChanged(Object entity,
                           String variableName)
```
    Parameters:
    
    entity - never null, an instance of a PlanningEntity class
    
    variableName - never null, either a genuine or shadow PlanningVariable
  - afterVariableChanged
```
void afterVariableChanged(Object entity,
                          String variableName)
```
    Parameters:
    
    entity - never null, an instance of a PlanningEntity class
    
    variableName - never null, either a genuine or shadow PlanningVariable
  - beforeEntityRemoved
```
void beforeEntityRemoved(Object entity)
```
    Parameters:
    
    entity - never null, an instance of a PlanningEntity class
  - afterEntityRemoved
```
void afterEntityRemoved(Object entity)
```
    Parameters:
    
    entity - never null, an instance of a PlanningEntity class
  - calculateScore
```
Score_ calculateScore()
```
    This method is only called if the Score cannot be predicted. The Score can be predicted for example after an undo Move.
    
    Returns:
    
    never null
