ScoreDirectorFactoryService (OptaPlanner Javadoc 8.17.0.Final API)

Type Parameters:

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

Score_ - the score type to go with the solution

All Known Implementing Classes:

ConstraintStreamsScoreDirectorFactoryService, DrlScoreDirectorFactoryService, EasyScoreDirectorFactoryService, IncrementalScoreDirectorFactoryService
```
public interface ScoreDirectorFactoryService<Solution_,Score_ extends Score<Score_>>
```
All ScoreDirectorFactory implementations must provide an implementation of this interface, as well as an entry in META-INF/services/org.optaplanner.core.impl.score.director.ScoreDirectorFactoryService file. This makes it available for discovery in ScoreDirectorFactoryFactory via ServiceLoader.

- Method Detail
  - getSupportedScoreDirectorType
```
ScoreDirectorType getSupportedScoreDirectorType()
```
    Returns:
    
    never null, the score director type that is implemented by the factory
  - buildScoreDirectorFactory
```
Supplier<AbstractScoreDirectorFactory<Solution_,Score_>> buildScoreDirectorFactory(ClassLoader classLoader,
                                                                                         SolutionDescriptor<Solution_> solutionDescriptor,
                                                                                         ScoreDirectorFactoryConfig config)
```
    Returns a Supplier which returns new instance of a score director defined by getSupportedScoreDirectorType(). This is done so that the actual factory is only instantiated after all the configuration fail-fasts have been performed.
    
    Parameters:
    
    classLoader -
    
    solutionDescriptor - never null, solution descriptor provided by the solver
    
    config - never null, configuration to use for instantiating the factory
    
    Returns:
    
    null when this type is not configured
    
    Throws:
    
    IllegalStateException - if the configuration has an issue
