public final class BendableBigDecimalScore extends AbstractScore<BendableBigDecimalScore> implements FeasibilityScore<BendableBigDecimalScore>
Score is based on n levels of BigDecimal 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.

FeasibilityScoreSolution is feasible if it has no broken hard constraints.isFeasible in interface FeasibilityScore<BendableBigDecimalScore>public BendableBigDecimalScore add(BendableBigDecimalScore augment)
Scoreadd in interface Score<BendableBigDecimalScore>augment - value to be added to this Scorepublic BendableBigDecimalScore subtract(BendableBigDecimalScore subtrahend)
Scoresubtract in interface Score<BendableBigDecimalScore>subtrahend - value to be subtracted from this Scorepublic BendableBigDecimalScore multiply(double multiplicand)
ScoreMath.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.
multiply in interface Score<BendableBigDecimalScore>multiplicand - value to be multiplied by this Score.public BendableBigDecimalScore divide(double divisor)
ScoreMath.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.
divide in interface Score<BendableBigDecimalScore>divisor - value by which this Score is to be dividedpublic BendableBigDecimalScore power(double exponent)
ScoreMath.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.

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}
