public class SamplingCollector<T>
extends java.lang.Object
implements LazyResultConsumer<T>

Class that allows client code to only collect a sample of results from an Infinite SimpleReact Stream The SamplingCollector won't collect results itself, but hand of control to a consumer that can when Sampling triggered.
