Method Details

fireAndForget

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

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

Parameters:

facts - never null

Returns:

never null

getConstraintMetaModel

public abstract ConstraintMetaModel getConstraintMetaModel()

supportsConstraintMatching

public boolean supportsConstraintMatching()

buildDerivedScoreDirector

public abstract InnerScoreDirector<Solution_,Score_> buildDerivedScoreDirector(boolean lookUpEnabled,
 ConstraintMatchPolicy constraintMatchPolicy)

Description copied from interface: InnerScoreDirectorFactory

Like InnerScoreDirectorFactory.buildScoreDirector(boolean, ConstraintMatchPolicy), 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.

Parameters:

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

constraintMatchPolicy - how should the ScoreDirector implementation do ConstraintMatch, if at all.

Returns:

never null
