                                       ScoreImpactType scoreImpactType)

  - ### Method Detail

    - #### extractConstraintWeight

          public Score<?> extractConstraintWeight(Solution_ workingSolution)

    - #### assertCorrectImpact

          public void assertCorrectImpact(int impact)

    - #### assertCorrectImpact

          public void assertCorrectImpact(long impact)

    - #### assertCorrectImpact

          public void assertCorrectImpact(BigDecimal impact)

    - #### getConstraintFactory

          public ConstraintFactory getConstraintFactory()

      Description copied from interface: `Constraint`
      The `ConstraintFactory` that build this.
      Specified by:
        `getConstraintFactory` in interface `Constraint`
      Returns:
        never null

    - #### getConstraintPackage

          public String getConstraintPackage()

      Description copied from interface: `Constraint`
      The constraint package is the namespace of the constraint.

      When using a `ConstraintConfiguration`, it is equal to the `ConstraintWeight.constraintPackage()`.

      Specified by:
        `getConstraintPackage` in interface `Constraint`
      Returns:
        never null

    - #### getConstraintName

          public String getConstraintName()

      Description copied from interface: `Constraint`
      The constraint name. It might not be unique, but `Constraint.getConstraintId()` is unique.

      When using a `ConstraintConfiguration`, it is equal to the `ConstraintWeight.value()`.

      Specified by:
        `getConstraintName` in interface `Constraint`
      Returns:
        never null

    - #### getScoreImpactType

          public ScoreImpactType getScoreImpactType()
