@GwtCompatible public abstract class ForwardingIterator<T extends @Nullable java.lang.Object> extends ForwardingObject implements java.util.Iterator<T>An iterator which forwards all its method calls to another iterator. Subclasses should override one or more methods to modify the behavior of the backing iterator as desired per the decorator pattern.
defaultmethod warning: This class forwards calls to only some
defaultmethods. Specifically, it forwards calls only for methods that existed before
defaultmethods were introduced. For newer methods, like
forEachRemaining, it inherits their default implementations. When those implementations invoke methods, they invoke methods on the

delegateDescription copied from class:
ForwardingObjectReturns the backing delegate instance that methods are forwarded to. Abstract subclasses generally override this method with an abstract method that has a more specific return type, such as
ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.
