java.lang.Object
- org.optaplanner.core.api.score.AbstractScore<HardSoftLongScore>
- - org.optaplanner.core.api.score.buildin.hardsoftlong.HardSoftLongScore

All Implemented Interfaces:

Serializable, Comparable<HardSoftLongScore>, FeasibilityScore<HardSoftLongScore>, Score<HardSoftLongScore>
```
public final class HardSoftLongScore
extends AbstractScore<HardSoftLongScore>
implements FeasibilityScore<HardSoftLongScore>
```
This Score is based on 2 levels of long constraints: hard and soft. Hard constraints have priority over soft constraints.
This class is immutable.

- Method Detail
  - parseScore
```
public static HardSoftLongScore parseScore(String scoreString)
```
  - valueOf
```
public static HardSoftLongScore valueOf(long hardScore,
                        long softScore)
```
  - getHardScore
```
public long getHardScore()
```
    The total of the broken negative hard constraints and fulfilled positive hard constraints. Their weight is included in the total. The hard score is usually a negative number because most use cases only have negative constraints.
    
    Returns:
    higher is better, usually negative, 0 if no hard constraints are broken/fulfilled
  - getSoftScore
```
public long getSoftScore()
```
    The total of the broken negative soft constraints and fulfilled positive soft constraints. Their weight is included in the total. The soft score is usually a negative number because most use cases only have negative constraints.
    In a normal score comparison, the soft score is irrelevant if the 2 scores don't have the same hard score.
    
    Returns:
    higher is better, usually negative, 0 if no soft constraints are broken/fulfilled
  - isFeasible
```
public boolean isFeasible()
```
    Description copied from interface: FeasibilityScore
    
    A Solution is feasible if it has no broken hard constraints.
    
    Specified by:
    
    isFeasible in interface FeasibilityScore<HardSoftLongScore>
    
    Returns:
    true if the hard score is 0 or higher
  - add
```
public HardSoftLongScore add(HardSoftLongScore augment)
```
    Description copied from interface: Score
    
    Returns a Score whose value is (this + augment).
    
    Specified by:
    
    add in interface Score<HardSoftLongScore>
    
    Parameters:
    augment - value to be added to this Score
    
    Returns:
    this + augment
  - subtract
```
public HardSoftLongScore subtract(HardSoftLongScore subtrahend)
```
    Description copied from interface: Score
    
    Returns a Score whose value is (this - subtrahend).
    
    Specified by:
    
    subtract in interface Score<HardSoftLongScore>
    
    Parameters:
    subtrahend - value to be subtracted from this Score
    
    Returns:
    this - subtrahend, rounded as necessary
  - multiply
```
public HardSoftLongScore multiply(double multiplicand)
```
    Description copied from interface: Score
    
    Returns a Score whose value is (this * multiplicand). When rounding is needed, it should be floored (as defined by 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.
    
    Specified by:
    
    multiply in interface Score<HardSoftLongScore>
    
    Parameters:
    multiplicand - value to be multiplied by this Score.
    
    Returns:
    this * multiplicand
  - divide
```
public HardSoftLongScore divide(double divisor)
```
    Description copied from interface: Score
    
    Returns a Score whose value is (this / divisor). When rounding is needed, it should be floored (as defined by 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.
    
    Specified by:
    
    divide in interface Score<HardSoftLongScore>
    
    Parameters:
    divisor - value by which this Score is to be divided
    
    Returns:
    this / divisor
  - power
```
public HardSoftLongScore power(double exponent)
```
    Description copied from interface: Score
    
    Returns a Score whose value is (this ^ exponent). When rounding is needed, it should be floored (as defined by 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.
    
    Specified by:
    
    power in interface Score<HardSoftLongScore>
    
    Parameters:
    exponent - value by which this Score is to be powered
    
    Returns:
    this ^ exponent
  - negate
```
public HardSoftLongScore negate()
```
    Description copied from interface: Score
    
    Returns a Score whose value is (- this).
    
    Specified by:
    
    negate in interface Score<HardSoftLongScore>
    
    Returns:
    - this
  - toLevelNumbers
```
public Number[] toLevelNumbers()
```
    Description copied from interface: Score
    
    Returns 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 specific Score implementation.
    For example: -0hard/-7soft returns new int{-0, -7}
    
    Specified by:
    
    toLevelNumbers in interface Score<HardSoftLongScore>
    
    Returns:
    never null
  - equals

public boolean equals(Object o)
```
    Overrides:
    
    equals in class Object
  - hashCode
```
public int hashCode()
```
    Overrides:
    
    hashCode in class Object
  - compareTo
```
public int compareTo(HardSoftLongScore other)
```
    Specified by:
    
    compareTo in interface Comparable<HardSoftLongScore>
