buildScoreDirector

public BavetConstraintStreamScoreDirector<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

See Also:

• InnerScoreDirector.isConstraintMatchEnabled()
• InnerScoreDirector.getConstraintMatchTotalMap()

buildDerivedScoreDirector

public InnerScoreDirector<Solution_,Score_> buildDerivedScoreDirector(boolean lookUpEnabled,
 boolean constraintMatchEnabledPreference)

Description copied from interface: InnerScoreDirectorFactory

Like InnerScoreDirectorFactory.buildScoreDirector(boolean, boolean), but makes the score director a derived one. Derived score directors may make choices which the main score director can not make, such as reducing logging. Derived score directors are typically used for multithreaded solving, testing and assert modes.

Specified by:

buildDerivedScoreDirector in interface InnerScoreDirectorFactory<Solution_,Score_ extends Score<Score_>>

Specified by:

buildDerivedScoreDirector in class AbstractConstraintStreamScoreDirectorFactory<Solution_,Score_ extends Score<Score_>>

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.

Returns:

never null

See Also:

• InnerScoreDirector.isConstraintMatchEnabled()
• InnerScoreDirector.getConstraintMatchTotalMap()

newSession

public BavetConstraintSession<Score_> newSession(Solution_ workingSolution,
 boolean constraintMatchEnabled,
 boolean scoreDirectorDerived)

fireAndForget

public AbstractScoreInliner<Score_> fireAndForget(Object... facts)

Description copied from class: AbstractConstraintStreamScoreDirectorFactory

Creates a new score director, inserts facts and calculates score.

Specified by:

fireAndForget in class AbstractConstraintStreamScoreDirectorFactory<Solution_,Score_ extends Score<Score_>>

Parameters:

facts - never null

Returns:

never null

getConstraintMetaModel

public ConstraintMetaModel getConstraintMetaModel()

Specified by:

getConstraintMetaModel in class AbstractConstraintStreamScoreDirectorFactory<Solution_,Score_ extends Score<Score_>>
