Description copied from interface: ScoreHolder

Extracts the Score, calculated by the KieSession for DroolsScoreDirector.

Should not be called directly, use ScoreDirector.calculateScore() instead.

Parameters:

initScore - <= 0, managed by OptaPlanner, needed as a parameter in the Score's creation method, see Score.getInitScore()

Returns:

never null, the Score of the working PlanningSolution
