Abstract Value Members
- abstract def aggregate(values: Seq[Value]): Seq[Value]
Aggregates the quantities of a sequence of values if allowable.
Aggregates the quantities of a sequence of values if allowable. If aggregation is not allowable, the values are returned unchanged. Whether aggregation is allowable depends on the implementation.
- values
The values to aggregate
- returns
The aggregated values
- abstract def aggregateWithChange(values: Seq[Value], amount: Option[BigInt]): (Seq[Value], Seq[Value])
Aggregates the quantities of a sequence of values if allowable, and given an amount, partitions the result of aggregation into 2 groups: the values that satisfy the amount and the change values that do not.
Aggregates the quantities of a sequence of values if allowable, and given an amount, partitions the result of aggregation into 2 groups: the values that satisfy the amount and the change values that do not.
If aggregation is not allowable, the values are returned unchanged and there will be no change. If amount is not specified OR the quantities are not enough to satisfy the amount, there will be no change
- values
The values to aggregate
- amount
The amount used to calculate change
- returns
The aggregated values and the change values
