public abstract class AggregatorCollection<N extends Number>
extends Object

Do not cache instances of this class! The methods BigAggregator.getCollection(), ComplexAggregator.getCollection() and PrimitiveAggregator.getCollection() return threadlocal instances, and when you access the individual aggregators they are AggregatorFunction.reset() for you.
