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.

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.

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}
