    - #### penalize

          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

          void penalize​(org.kie.api.runtime.rule.RuleContext kcontext,
                        BigDecimal hardWeightMultiplier,
                        BigDecimal softWeightMultiplier)

      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
        `hardWeightMultiplier` - at least 0
        `softWeightMultiplier` - at least 0

    - #### reward

          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

          void reward​(org.kie.api.runtime.rule.RuleContext kcontext,
                      BigDecimal hardWeightMultiplier,
                      BigDecimal softWeightMultiplier)

      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
        `hardWeightMultiplier` - at least 0
        `softWeightMultiplier` - at least 0

    - #### impactScore

          void impactScore​(org.kie.api.runtime.rule.RuleContext kcontext,
                           BigDecimal weightMultiplier)

    - #### addHardConstraintMatch

          void addHardConstraintMatch​(org.kie.api.runtime.rule.RuleContext kcontext,
                                      BigDecimal hardWeight)

      Parameters:
        `kcontext` - never null, the magic variable in DRL
        `hardWeight` - never null, higher is better, negative for a penalty, positive for a reward

    - #### addSoftConstraintMatch

          void addSoftConstraintMatch​(org.kie.api.runtime.rule.RuleContext kcontext,
                                      BigDecimal softWeight)

      Parameters:
        `kcontext` - never null, the magic variable in DRL
        `softWeight` - never null, higher is better, negative for a penalty, positive for a reward

    - #### addMultiConstraintMatch

          void addMultiConstraintMatch​(org.kie.api.runtime.rule.RuleContext kcontext,
                                       BigDecimal hardWeight,
                                       BigDecimal softWeight)

      Parameters:
        `kcontext` - never null, the magic variable in DRL
        `hardWeight` - never null, higher is better, negative for a penalty, positive for a reward
        `softWeight` - never null, higher is better, negative for a penalty, positive for a reward
