All Implemented Interfaces:

Iterator<T>

@GwtCompatible
public abstract class AbstractSequentialIterator<T>
extends UnmodifiableIterator<T>

This class provides a skeletal implementation of the Iterator interface for sequences whose next element can always be derived from the previous element. Null elements are not supported, nor is the UnmodifiableIterator.remove() method.

Example:

   

   Iterator<Integer> powersOfTwo = 
       new AbstractSequentialIterator<Integer>(1) {
         protected Integer computeNext(Integer previous) {
           return (previous == 1 << 30) ? null : previous * 2;
         }
       };

Since:

12.0 (in Guava as AbstractLinkedIterator since 8.0)
