org.optaplanner.core.api.score.buildin.hardsoftbigdecimal.HardSoftBigDecimalScore
public final class HardSoftBigDecimalScore
This Score
is based on 2 levels of BigDecimal
constraints: hard and soft.
Hard constraints have priority over soft constraints.

public HardSoftBigDecimalScore add(HardSoftBigDecimalScore augment)
Score
add
in interface Score<HardSoftBigDecimalScore>
augment
- value to be added to this Score
public HardSoftBigDecimalScore subtract(HardSoftBigDecimalScore subtrahend)
Score
subtract
in interface Score<HardSoftBigDecimalScore>
subtrahend
- value to be subtracted from this Score
public HardSoftBigDecimalScore multiply(double multiplicand)
Score
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.
multiply
in interface Score<HardSoftBigDecimalScore>
multiplicand
- value to be multiplied by this Score.
public HardSoftBigDecimalScore divide(double divisor)
Score
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.
divide
in interface Score<HardSoftBigDecimalScore>
divisor
- value by which this Score is to be divided
public HardSoftBigDecimalScore power(double exponent)
Score
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.
power
in interface Score<HardSoftBigDecimalScore>
exponent
- value by which this Score is to be powered

.
The length of the returned array must be stable for a specific Score
implementation.
For example: -0hard/-7soft returns new int{-0, -7}
