public final class HardMediumSoftBigDecimalScore extends AbstractScore<HardMediumSoftBigDecimalScore> implements FeasibilityScore<HardMediumSoftBigDecimalScore>
Score
is based on 3 levels of BigDecimal
constraints: hard, medium and soft.
Hard constraints have priority over medium constraints.
Medium constraints have priority over soft constraints.
Hard constraints determine feasibility.
This class is immutable.

public BigDecimal getMediumScore()
In a normal score comparison, the medium score is irrelevant if the 2 scores don't have the same hard score.
public BigDecimal getSoftScore()
In a normal score comparison, the soft score is irrelevant if the 2 scores don't have the same hard and medium score.

- value to be added to this Scorepublic HardMediumSoftBigDecimalScore subtract(HardMediumSoftBigDecimalScore subtrahend)
Score

in interface Score<HardMediumSoftBigDecimalScore>
subtrahend
- value to be subtracted from this Scorepublic HardMediumSoftBigDecimalScore 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<HardMediumSoftBigDecimalScore>
multiplicand
- value to be multiplied by this Score.public HardMediumSoftBigDecimalScore 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<HardMediumSoftBigDecimalScore>
divisor
- value by which this Score is to be dividedpublic HardMediumSoftBigDecimalScore 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<HardMediumSoftBigDecimalScore>
exponent
- value by which this Score is to be poweredpublic HardMediumSoftBigDecimalScore negate()
Score

in interface Score<HardMediumSoftBigDecimalScore>
public Number[] toLevelNumbers()
Score
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}

in interface Score<HardMediumSoftBigDecimalScore>
ScoreDefinition.fromLevelNumbers(int, Number[])
public int compareTo(HardMediumSoftBigDecimalScore other)
compareTo
in interface Comparable<HardMediumSoftBigDecimalScore>
public String toShortString()
Score
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.
