public abstract static class ObjectIterators.AbstractIndexBasedIterator<K> extends AbstractObjectIterator<K>
A skeletal implementation for an iterator backed by an index-based data store. High performance concrete implementations (like the main Iterator of ArrayList) generally should avoid using this and just implement the interface directly, but should be decent for less performance critical implementations.This class is only appropriate for sequences that are at most
Integer.MAX_VALUE
long. If your backing data store can be bigger then this, consider the equivalently named class in the type specificBigListIterators
class.As the abstract methods in this class are used in inner loops, it is generally a good idea to override the class as
final
as to encourage the JVM to inline them (or alternatively, override the abstract methods as final).

Description copied from interface:ObjectIterator
Skips the given number of elements.The effect of this call is exactly the same as that of calling
Iterator.next()
forn
times (possibly stopping ifIterator.hasNext()
becomes false).- Parameters:
n
- the number of elements to skip.- Returns:
- the number of elements actually skipped.

Iterator.next()
