Class CloneListIterator<E>

  • Type Parameters:
    E - the type of elements returned by the iterator
    All Implemented Interfaces:
    Iterator<E>, ListIterator<E>
    public class CloneListIterator<E>
extends Object
implements ListIterator<E>
    A CloneListIterator iterates over a copy of a list, allowing for concurrent access to the original list.

    The original list passed to the CloneListIterator's constructor should be synchronized; otherwise you run the risk of a corrupted list (e.g. Vector.

    By default, a CloneListIterator does not support the modification operations; this is because it does not have access to the original list. But if the CloneListIterator is supplied with a CloneListIterator.Mutator it will delegate the modification operations to the CloneListIterator.Mutator. Alternatively, a subclass can override the modification methods.
