Constructor Detail

AbstractScoreHolder

protected AbstractScoreHolder(boolean constraintMatchEnabled,
                              Score_ zeroScore)

Method Detail

isConstraintMatchEnabled

public boolean isConstraintMatchEnabled()

getConstraintMatchTotalMap

public Map<String,ConstraintMatchTotal<Score_>> getConstraintMatchTotalMap()

getIndictmentMap

public Map<Object,Indictment<Score_>> getIndictmentMap()

configureConstraintWeight

public void configureConstraintWeight(org.kie.api.definition.rule.Rule rule,
                                      Score_ constraintWeight)

registerConstraintMatch

protected void registerConstraintMatch(org.kie.api.runtime.rule.RuleContext kcontext,
                                       Runnable constraintUndoListener,
                                       Supplier<Score_> scoreSupplier)

Requires @OptaPlannerRuleEventListener to be added as event listener on KieSession, otherwise the score changes caused by the constraint matches would not be undone. See DroolsScoreDirector.resetKieSession() for an example.

Parameters:

kcontext - The rule for which to register the match.

constraintUndoListener - The operation to run to undo the match.

scoreSupplier - The score change to be undone when constraint justification enabled.

impactScore

public void impactScore(org.kie.api.runtime.rule.RuleContext kcontext)

For internal use only, use penalize() or reward() instead.

Parameters:

kcontext - never null

impactScore

public abstract void impactScore(org.kie.api.runtime.rule.RuleContext kcontext,
                                 int weightMultiplier)

For internal use only, use penalize() or reward() instead.

Parameters:

                                 long weightMultiplier)

For internal use only, use penalize() or reward() instead.

Parameters:

public abstract Score_ extractScore(int initScore)

extractJustificationList

protected List<Object> extractJustificationList(org.kie.api.runtime.rule.RuleContext kcontext)
