ScoreManager (OptaPlanner distribution 7.60.0.Final API)

Type Parameters:

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

All Known Implementing Classes:

DefaultScoreManager
```
public interface ScoreManager<Solution_>
```
A stateless service to help calculate Score, ConstraintMatchTotal, Indictment, etc.
To create a ScoreManager, use create(SolverFactory).
These methods are thread-safe unless explicitly stated otherwise.

Method Summary

All Methods Static Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`static <Solution_> ScoreManager<Solution_>`	`create(SolverFactory<Solution_> solverFactory)`	Uses a `SolverFactory` to build a `ScoreManager`.
`String`	`explainScore(Solution_ solution)`	Returns a diagnostic text that explains the solution through the `ConstraintMatch` API to identify which constraints or planning entities cause that score quality.
`Score`	`updateScore(Solution_ solution)`	Calculates the `Score` of a `PlanningSolution` and updates its `PlanningScore` member.

```
static <Solution_> ScoreManager<Solution_> create(SolverFactory<Solution_> solverFactory)
```
    Uses a SolverFactory to build a ScoreManager.
    
    Type Parameters:
    
    Solution_ - the solution type, the class with the PlanningSolution annotation
    
    Parameters:
    
    solverFactory - never null
    
    Returns:
    
    never null
  - updateScore
```
Score updateScore(Solution_ solution)
```
    Calculates the Score of a PlanningSolution and updates its PlanningScore member.
    
    Parameters:
    
    solution - never null
  - explainScore
```
String explainScore(Solution_ solution)
```
    Returns a diagnostic text that explains the solution through the ConstraintMatch API to identify which constraints or planning entities cause that score quality. In case of an infeasible solution, this can help diagnose the cause of that.
    Do not parse this string. Instead, to provide this information in a UI or a service, use SolverFactory.getScoreDirectorFactory() to retrieve ScoreDirector.getConstraintMatchTotalMap() and ScoreDirector.getIndictmentMap() and convert those into a domain specific API.
    This method is thread-safe.
    
    Returns:
    
    null if updateScore(Object) returns null with the same solution
