public abstract class ForwardingIterator<T> extends ForwardingObject implements java.util.Iterator<T>
default method warning: This class forwards calls to only some default methods. Specifically, it forwards calls only for methods that existed before default
methods were introduced. For newer methods, like forEachRemaining, it inherits their
default implementations. When those implementations invoke methods, they invoke methods on the
ForwardingIterator.
