Direct Known Subclasses:

public abstract class AggregatorSet<N extends java.lang.Comparable<N>>
extends java.lang.Object

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