public abstract class ForwardingListIterator<E extends @Nullable Object>
extends ForwardingIterator<E>
implements ListIterator<E>
A list iterator which forwards all its method calls to another list iterator. Subclasses should
override one or more methods to modify the behavior of the backing iterator as desired per the decorator pattern.
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 ForwardingListIterator
.

delegate
Description copied from class:ForwardingObject
Returns 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 asForwardingSet.delegate()
. Concrete subclasses override this method to supply the instance being decorated.- Specified by:
