All Implemented Interfaces:

java.io.Closeable, Generator<E>, Resettable, ThreadAware

public class SkipGeneratorProxy<E>
extends GeneratorProxy<E>

This forwards a source generator's products. Iterates through the products of another generator with a variable step width. This is intended mainly for use with importing generators that provide data volumes too big to keep in RAM.
