public abstract class AbstractEnumerable<T>
extends DefaultEnumerable<T>

Abstract implementation of the Enumerable interface that implements the extension methods.

It is helpful to derive from this class if you are implementing Enumerable, because Enumerable has so many extension methods, but it is not required.
