## Class BendableLongScore

- java.lang.Object
- - org.optaplanner.core.api.score.AbstractScore<S>
  - - org.optaplanner.core.api.score.AbstractBendableScore<BendableLongScore>
    - - org.optaplanner.core.api.score.buildin.bendablelong.BendableLongScore

- All Implemented Interfaces:
    Serializable, Comparable<BendableLongScore>, FeasibilityScore<BendableLongScore>, Score<BendableLongScore>

      public final class BendableLongScore
      extends AbstractBendableScore<BendableLongScore>
      implements FeasibilityScore<BendableLongScore>

  This `Score` is based on n levels of long constraints. The number of levels is bendable at configuration time.

  This class is immutable.

  The `getHardLevelsSize()` and `getSoftLevelsSize()` must be the same as in the `BendableLongScoreDefinition` used.

      Returns a Score whose value is (this * multiplicand). When rounding is needed, it should be floored (as defined by `Math.floor(double)`).

      If the implementation has a scale/precision, then the unspecified scale/precision of the double multiplicand should have no impact on the returned scale/precision.

      Specified by:
        `multiply` in interface `Score<BendableLongScore>`
      Parameters:
        `multiplicand` - value to be multiplied by this Score.
      Returns:
        this * multiplicand

    - #### divide

          public BendableLongScore divide(double divisor)

      Description copied from interface: `Score`
      Returns a Score whose value is (this / divisor). When rounding is needed, it should be floored (as defined by `Math.floor(double)`).

      If the implementation has a scale/precision, then the unspecified scale/precision of the double divisor should have no impact on the returned scale/precision.

      Specified by:
        `divide` in interface `Score<BendableLongScore>`
      Parameters:
        `divisor` - value by which this Score is to be divided
      Returns:
        this / divisor

    - #### power

          public BendableLongScore power(double exponent)

      Description copied from interface: `Score`
      Returns a Score whose value is (this ^ exponent). When rounding is needed, it should be floored (as defined by `Math.floor(double)`).

      If the implementation has a scale/precision, then the unspecified scale/precision of the double exponent should have no impact on the returned scale/precision.

      Specified by:
        `power` in interface `Score<BendableLongScore>`
      Parameters:
        `exponent` - value by which this Score is to be powered
      Returns:
        this ^ exponent

    - #### negate

          public BendableLongScore negate()

      Description copied from interface: `Score`
      Returns a Score whose value is (- this).
      Specified by:
        `negate` in interface `Score<BendableLongScore>`
      Returns:
        - this

    - #### toLevelNumbers

          public Number[] toLevelNumbers()

      Description copied from interface: `Score`
      Returns an array of numbers representing the Score. Each number represents 1 score level. A greater score level uses a lower array index than a lesser score level.

      When rounding is needed, each rounding should be floored (as defined by `Math.floor(double)`). The length of the returned array must be stable for a specific `Score` implementation.

      For example: `-0hard/-7soft` returns `new int{-0, -7}`

      The level numbers do not contain the `Score.getInitScore()`. For example: `-3init/-0hard/-7soft` also returns `new int{-0, -7}`

      Specified by:
        `toLevelNumbers` in interface `Score<BendableLongScore>`
      Returns:
        never null
      See Also:

      Overrides:

    - #### compareTo

          public int compareTo(BendableLongScore other)

      Specified by:

    - #### toShortString

          public String toShortString()

      Description copied from interface: `Score`
      Like `Object.toString()`, but trims score levels which have a zero weight. For example 0hard/-258soft returns -258soft.

      Do not use this format to persist information as text, use `Object.toString()` instead, so it can be parsed reliably.

      Specified by:
        `toShortString` in interface `Score<BendableLongScore>`
      Returns:
        never null

    - #### toString

      Parameters:
        `otherScore` - never null
      Returns:
        true if the otherScore is accepted as a parameter of `Score.add(Score)`, `Score.subtract(Score)` and `Comparable.compareTo(Object)`.
