SimpleLongScoreDefinition

public SimpleLongScoreDefinition()

Method Detail

getFeasibleLevelsSize

public int getFeasibleLevelsSize()

Description copied from interface: ScoreDefinition

Returns the number of levels of Score.toLevelNumbers(). that are used to determine Score.isFeasible().

Returns:

at least 0, at most ScoreDefinition.getLevelsSize()

getScoreClass

public Class<SimpleLongScore> 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 SimpleLongScore getZeroScore()

Description copied from interface: ScoreDefinition

The score that represents zero.

Returns:

never null

getOneSoftestScore

public SimpleLongScore getOneSoftestScore()

Description copied from interface: ScoreDefinition

The score that represents the softest possible one.

Returns:

never null

parseScore

public SimpleLongScore 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), ScoreUtils.parseScore(Class, String)

fromLevelNumbers

public SimpleLongScore 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.getInitScore()

levelNumbers - never null

Returns:

never null

buildOptimisticBound

public SimpleLongScore buildOptimisticBound(InitializingScoreTrend initializingScoreTrend,
                                            SimpleLongScore 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.getInitScore() 0.

Returns:

never null

buildPessimisticBound

public SimpleLongScore buildPessimisticBound(InitializingScoreTrend initializingScoreTrend,
                                             SimpleLongScore 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.getInitScore() 0

Returns:

never null

divideBySanitizedDivisor

public SimpleLongScore divideBySanitizedDivisor(SimpleLongScore dividend,
                                                SimpleLongScore 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
