Module ojalgo

Package org.ojalgo.function.aggregator

Class AggregatorSet<N extends Comparable<N>>

java.lang.Object

org.ojalgo.function.aggregator.AggregatorSet<N>

Direct Known Subclasses:

BigAggregator, ComplexAggregator, PrimitiveAggregator, QuadrupleAggregator, QuaternionAggregator, RationalAggregator

public abstract class AggregatorSet<N extends Comparable<N>>
extends 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.
