      • add

        public BendableLongScore add​(BendableLongScore addend)
        Description copied from interface: Score
        Returns a Score whose value is (this + addend).
        Parameters:
        addend - value to be added to this Score
        Returns:

      • subtract

        public BendableLongScore subtract​(BendableLongScore subtrahend)
        Description copied from interface: Score
        Returns a Score whose value is (this - subtrahend).
        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: 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.

        Parameters:
        multiplicand - value to be multiplied by this Score.
        Returns:
        this * multiplicand
      • divide

        public BendableLongScore 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.

        Parameters:
        divisor - value by which this Score is to be divided
        Returns:
        this / divisor
      • power

        public BendableLongScore 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.

        Parameters:
        exponent - value by which this Score is to be powered
        Returns:
        this ^ exponent
      • negate

        public BendableLongScore negate()
        Description copied from interface: Score
        Returns a Score whose value is (- this).
        Returns:
        - this
      • abs

        public BendableLongScore abs()
        Description copied from interface: Score
        Returns a Score whose value is the absolute value of the score, i.e. |this|.
        Returns:
        never null
      • zero

        public BendableLongScore zero()
        Description copied from interface: Score
        Returns a Score, all levels of which are zero.
        Returns:
        never null
      • 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}

        The level numbers do not contain the Score.getInitScore(). For example: -3init/-0hard/-7soft also returns new int{-0, -7}

        Returns:
        never null
      • hashCode

        public int hashCode()
        Overrides:
        hashCode in class Object
      • toShortString

        public String toShortString()
        Description copied from interface: Score
        Like Object.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.

        Returns:
        never null
