HardMediumSoftLongScoreDefinition

public HardMediumSoftLongScoreDefinition()

Method Details

getLevelsSize

public int getLevelsSize()

Description copied from interface: ScoreDefinition

Returns the length of Score.toLevelNumbers() for every Score of this definition. For example: returns 2 on HardSoftScoreDefinition.

Specified by:

getLevelsSize in interface ScoreDefinition<HardMediumSoftLongScore>

Overrides:

getLevelsSize in class AbstractScoreDefinition<HardMediumSoftLongScore>

Returns:

at least 1

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<HardMediumSoftLongScore> 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 HardMediumSoftLongScore getZeroScore()

Description copied from interface: ScoreDefinition

The score that represents zero.

Returns:

never null

getOneSoftestScore

public HardMediumSoftLongScore getOneSoftestScore()

Description copied from interface: ScoreDefinition

The score that represents the softest possible one.

Returns:

never null

parseScore

public HardMediumSoftLongScore parseScore(String scoreString)

Description copied from interface: ScoreDefinition

Parses the String and returns a Score.

Parameters:

scoreString - never null

Returns:

never null

fromLevelNumbers

public HardMediumSoftLongScore fromLevelNumbers(Number[] levelNumbers)

Description copied from interface: ScoreDefinition

The opposite of Score.toLevelNumbers().

Parameters:

levelNumbers - never null

Returns:

never null

buildOptimisticBound

public HardMediumSoftLongScore buildOptimisticBound(InitializingScoreTrend initializingScoreTrend,
 HardMediumSoftLongScore 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, considered initialized

Returns:

never null

buildPessimisticBound

public HardMediumSoftLongScore buildPessimisticBound(InitializingScoreTrend initializingScoreTrend,
 HardMediumSoftLongScore 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, considered initialized

Returns:

never null

divideBySanitizedDivisor

public HardMediumSoftLongScore divideBySanitizedDivisor(HardMediumSoftLongScore dividend,
 HardMediumSoftLongScore 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

getNumericType

public Class<?> getNumericType()

Description copied from interface: ScoreDefinition

Return the type of number that the score implementation operates on. Examples:

• int.class for SimpleScore
• BigDecimal.class for SimpleBigDecimalScore

Returns:

never null
