All Implemented Interfaces:

```
Class ListIterator, iterates over a sequence of items held in a Java List.
Note: There are three subclasses: ListIterator, which takes a general list of items, NodeListIterator, which takes a list of nodes, and AtomicListIterator, which takes a list of atomic values. It might seem simpler to implement this entirely using generics, but that design proves very difficult to translate to C#, where generics behave very differently. With this approach the generics are confined to this abstract class.

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`static class`	`ListIterator.Of<T extends Item>`
`static class`	`ListIterator.OfAtomic<A extends AtomicValue>`	ListIterator.OfAtomic is a subclass of ListIterator where the list always contains atomic values; it therefore implements the AtomicIterator interface.

    Description copied from interface: LookaheadIterator
    
    Ask whether the hasNext() method can be called. This method must be called before calling hasNext(), because some iterators implement this interface, but only support look-ahead under particular circumstances (this is usually because they delegate to another iterator)
    
    Specified by:
    
    supportsHasNext in interface LookaheadIterator
    
    Returns:
    
    true if the LookaheadIterator.hasNext() method is available
