Class ForwardingListIterator<E extends @Nullable java.lang.Object>

  • All Implemented Interfaces:
    java.util.Iterator<E>, java.util.ListIterator<E>
    @GwtCompatible
public abstract class ForwardingListIterator<E extends @Nullable java.lang.Object>
extends ForwardingIterator<E>
implements java.util.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.

    • Method Detail

      • delegate

        protected abstract java.util.ListIterator<E> 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 as ForwardingSet.delegate(). Concrete subclasses override this method to supply the instance being decorated.
