      • penalize

        public void penalize​(org.kie.api.runtime.rule.RuleContext kcontext)
        Penalize a match by the ConstraintWeight negated.
        Parameters:
        kcontext - never null, the magic variable in DRL
      • penalize

        public void penalize​(org.kie.api.runtime.rule.RuleContext kcontext,
                             BigDecimal weightMultiplier)
        Penalize a match by the ConstraintWeight negated and multiplied with the weightMultiplier for all score levels.
        Parameters:
        kcontext - never null, the magic variable in DRL
        weightMultiplier - at least 0
      • penalize

        public void penalize​(org.kie.api.runtime.rule.RuleContext kcontext,
                             BigDecimal[] hardWeightsMultiplier,
                             BigDecimal[] softWeightsMultiplier)
        Penalize a match by the ConstraintWeight negated and multiplied with the specific weightMultiplier per score level. Slower than penalize(RuleContext, BigDecimal).
        Parameters:
        kcontext - never null, the magic variable in DRL
        hardWeightsMultiplier - elements at least 0
        softWeightsMultiplier - elements at least 0
      • reward

        public void reward​(org.kie.api.runtime.rule.RuleContext kcontext)
        Reward a match by the ConstraintWeight.
        Parameters:
        kcontext - never null, the magic variable in DRL
      • reward

        public void reward​(org.kie.api.runtime.rule.RuleContext kcontext,
                           BigDecimal weightMultiplier)
        Reward a match by the ConstraintWeight multiplied with the weightMultiplier for all score levels.
        Parameters:
        kcontext - never null, the magic variable in DRL
        weightMultiplier - at least 0
      • reward

        public void reward​(org.kie.api.runtime.rule.RuleContext kcontext,
                           BigDecimal[] hardWeightsMultiplier,
                           BigDecimal[] softWeightsMultiplier)
        Reward a match by the ConstraintWeight multiplied with the specific weightMultiplier per score level. Slower than reward(RuleContext, BigDecimal).
        Parameters:
        kcontext - never null, the magic variable in DRL
        hardWeightsMultiplier - elements at least 0
        softWeightsMultiplier - elements at least 0
      • addHardConstraintMatch

        public void addHardConstraintMatch​(org.kie.api.runtime.rule.RuleContext kcontext,
                                           int hardLevel,
                                           BigDecimal weight)
        Parameters:
        kcontext - never null, the magic variable in DRL
        hardLevel - 0 <= hardLevel < getHardLevelsSize(). The scoreLevel is hardLevel for hard levels and softLevel + hardLevelSize for soft levels.
        weight - never null, higher is better, negative for a penalty, positive for a reward
      • addSoftConstraintMatch

        public void addSoftConstraintMatch​(org.kie.api.runtime.rule.RuleContext kcontext,
                                           int softLevel,
                                           BigDecimal weight)
        Parameters:
        kcontext - never null, the magic variable in DRL
        softLevel - 0 <= softLevel < getSoftLevelsSize(). The scoreLevel is hardLevel for hard levels and softLevel + hardLevelSize for soft levels.
        weight - never null, higher is better, negative for a penalty, positive for a reward
