- All Implemented Interfaces:
IBendableScore<BendableLongScore>,Score<BendableLongScore>,Serializable,Comparable<BendableLongScore>
public final class BendableLongScore extends Object implements IBendableScore<BendableLongScore>
ThisScoreis based on n levels of long constraints. The number of levels is bendable at configuration time.This class is immutable.

initScore
public int initScore()
Description copied from interface:ScoreThe init score is the negative of the number of uninitialized genuine planning variables. If it's 0 (which it usually is), thePlanningSolutionis fully initialized and the score'sObject.toString()does not mention it.During
Comparable.compareTo(Object), it's even more important than the hard score: if you don't want this behaviour, read about overconstrained planning in the reference manual.- Specified by:

-

-
isFeasible
public boolean isFeasible()
Description copied from interface:ScoreAPlanningSolutionis feasible if it has no broken hard constraints andScore.isSolutionInitialized()is true. Simple scores (SimpleScore,SimpleLongScore,SimpleBigDecimalScore) are always feasible, if theirScore.initScore()is 0.- Specified by:
isFeasiblein interfaceScore<BendableLongScore>- Returns:

Score.initScore()is 0.
-
add
public BendableLongScore add(BendableLongScore addend)
Description copied from interface:ScoreReturns a Score whose value is (this + addend).- Specified by:
addin interfaceScore<BendableLongScore>- Parameters:
addend- value to be added to this Score- Returns:
- this + addend

subtractin interfaceScore<BendableLongScore>- Parameters:
subtrahend- value to be subtracted from this Score- Returns:
- this - subtrahend, rounded as necessary
-
multiply
public BendableLongScore multiply(double multiplicand)
Description copied from interface:ScoreReturns a Score whose value is (this * multiplicand). When rounding is needed, it should be floored (as defined byMath.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.
- Specified by:
multiplyin interfaceScore<BendableLongScore>- Parameters:
multiplicand- value to be multiplied by this Score.- Returns:
- this * multiplicand
-
divide
public BendableLongScore divide(double divisor)
Description copied from interface:ScoreReturns a Score whose value is (this / divisor). When rounding is needed, it should be floored (as defined byMath.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.
- Specified by:
dividein interfaceScore<BendableLongScore>- Parameters:
divisor- value by which this Score is to be divided- Returns:
- this / divisor
-
power
public BendableLongScore power(double exponent)
Description copied from interface:ScoreReturns a Score whose value is (this ^ exponent). When rounding is needed, it should be floored (as defined byMath.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.
- Specified by:
powerin interfaceScore<BendableLongScore>- Parameters:
exponent- value by which this Score is to be powered- Returns:
- this ^ exponent
-
negate
public BendableLongScore negate()
Description copied from interface:ScoreReturns a Score whose value is (- this).- Specified by:
negatein interfaceScore<BendableLongScore>- Returns:
- - this
-
abs
public BendableLongScore abs()
Description copied from interface:ScoreReturns a Score whose value is the absolute value of the score, i.e. |this|.- Specified by:
absin interfaceScore<BendableLongScore>- Returns:
- never null
-
zero
public BendableLongScore zero()
Description copied from interface:ScoreReturns a Score, all levels of which are zero.- Specified by:
zeroin interfaceScore<BendableLongScore>- Returns:
- never null
-
toLevelNumbers
public Number[] toLevelNumbers()
Description copied from interface:ScoreReturns an array of numbers representing the Score. Each number represents 1 score level. A greater score level uses a lower array index than a lesser score level.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 specificScoreimplementation.For example:
-0hard/-7softreturnsnew int{-0, -7}The level numbers do not contain the
Score.initScore(). For example:-3init/-0hard/-7softalso returnsnew int{-0, -7}- Specified by:
toLevelNumbersin interfaceScore<BendableLongScore>- Returns:
- never null
-
compareTo
public int compareTo(BendableLongScore other)
- Specified by:
compareToin interfaceComparable<BendableLongScore>
-
toShortString
public String toShortString()
Description copied from interface:ScoreLikeObject.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.- Specified by:
toShortStringin interfaceScore<BendableLongScore>- Returns:
- never null
