BendableBigDecimalScoreDefinition

public BendableBigDecimalScoreDefinition(int hardLevelsSize,
 int softLevelsSize)

Method Details

getScoreClass

public Class<BendableBigDecimalScore> getScoreClass()

Description copied from interface: ScoreDefinition

Returns the Class of the actual Score implementation. For example: returns HardSoftScore.class on HardSoftScoreDefinition.

Returns:

never null

getZeroScore

public BendableBigDecimalScore getZeroScore()

Description copied from interface: ScoreDefinition

The score that represents zero.

Returns:

never null

getOneSoftestScore

public final BendableBigDecimalScore getOneSoftestScore()

Description copied from interface: ScoreDefinition

The score that represents the softest possible one.

Returns:

never null

parseScore

public BendableBigDecimalScore parseScore(String scoreString)

Description copied from interface: ScoreDefinition

Parses the String and returns a Score.

Parameters:

scoreString - never null

Returns:

never null

• ScoreDefinition.formatScore(Score)

fromLevelNumbers

public BendableBigDecimalScore fromLevelNumbers(int initScore,
 Number[] levelNumbers)

Description copied from interface: ScoreDefinition

The opposite of Score.toLevelNumbers().

Parameters:

initScore - <= 0, managed by OptaPlanner, needed as a parameter in the Score's creation method, see Score.initScore()

levelNumbers - never null

Returns:

never null

createScore

public BendableBigDecimalScore createScore(BigDecimal... scores)

createScoreUninitialized

public BendableBigDecimalScore createScoreUninitialized(int initScore,
 BigDecimal... scores)

buildOptimisticBound

public BendableBigDecimalScore buildOptimisticBound(InitializingScoreTrend initializingScoreTrend,
 BendableBigDecimalScore score)

Description copied from interface: ScoreDefinition

Builds a Score which is equal or better than any other Score with more variables initialized (while the already variables don't change).

Parameters:

initializingScoreTrend - never null, with InitializingScoreTrend.getLevelsSize() equal to ScoreDefinition.getLevelsSize().

score - never null, with Score.initScore() 0.

Returns:

never null

buildPessimisticBound

public BendableBigDecimalScore buildPessimisticBound(InitializingScoreTrend initializingScoreTrend,
 BendableBigDecimalScore score)

Description copied from interface: ScoreDefinition

Builds a Score which is equal or worse than any other Score with more variables initialized (while the already variables don't change).

Parameters:

initializingScoreTrend - never null, with InitializingScoreTrend.getLevelsSize() equal to ScoreDefinition.getLevelsSize().

score - never null, with Score.initScore() 0

Returns:

never null

divideBySanitizedDivisor

public BendableBigDecimalScore divideBySanitizedDivisor(BendableBigDecimalScore dividend,
 BendableBigDecimalScore divisor)

Description copied from interface: ScoreDefinition

Return Score whose every level is the result of dividing the matching levels in this and the divisor. When rounding is needed, it is floored (as defined by Math.floor(double)).

If any of the levels in the divisor are equal to zero, the method behaves as if they were equal to one instead.

divisor - value by which this Score is to be divided

Returns:

this / divisor
