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

This Score is based on n levels of int 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 BendableScoreDefinition used.

    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:

    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<BendableScore>
    
    Parameters:
    
    exponent - value by which this Score is to be powered

  - negate
```
public BendableScore negate()
```
    Description copied from interface: Score
    
    Returns a Score whose value is (- 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<BendableScore>
    
    Returns:
    
    never null

  - 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<BendableScore>
    
    Returns:
    
    never null

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