Method Detail

getScoreDirectorFactory

public ScoreDirectorFactory<Solution_> getScoreDirectorFactory()

updateScore

public Score updateScore(Solution_ solution)

Description copied from interface: ScoreManager

Calculates the Score of a PlanningSolution and updates its PlanningScore member.

Specified by:

updateScore in interface ScoreManager<Solution_>

Parameters:

solution - never null

explainScore

public String explainScore(Solution_ solution)

Description copied from interface: ScoreManager

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.

Specified by:

explainScore in interface ScoreManager<Solution_>

Returns:

null if ScoreManager.updateScore(Object) returns null with the same solution
