buildScoreDirector

public IncrementalScoreDirector<Solution_,Score_> buildScoreDirector(boolean lookUpEnabled,
 boolean constraintMatchEnabledPreference,
 boolean expectShadowVariablesInCorrectState)

Description copied from interface: InnerScoreDirectorFactory

Like InnerScoreDirectorFactory.buildScoreDirector(), but optionally disables ConstraintMatch tracking and look up for more performance (presuming the ScoreDirector implementation actually supports it to begin with).

Parameters:

lookUpEnabled - true if a ScoreDirector implementation should track all working objects for ScoreDirector.lookUpWorkingObject(Object)

constraintMatchEnabledPreference - false if a ScoreDirector implementation should not do ConstraintMatch tracking even if it supports it.

expectShadowVariablesInCorrectState - true, unless you have an exceptional reason. See InnerScoreDirector.expectShadowVariablesInCorrectState() for details.

Returns:

never null
