Class MutableIterator2<E>

java.lang.Object

de.thaw.comb.util.MutableIterator2<E>

All Implemented Interfaces:

Iterable<E>, Iterator<E>

public class MutableIterator2<E>
extends Object
implements Iterator<E>, Iterable<E>

Another attempt at an Iterator behaving like a FIFO queue. Adheres to the general contract of the Iterator, but is at the same Iterable so as to enable instances to work directly in foreach loops in an attempt to make the client's code a little cleaner.

This class offers methods to safely append items to the iterator while the iteration is ongoing. It also works directly on the collections added, which should yield runtime improvements over MutableIterator.

However, this class is still not ideal for the Combiner's split queue (for which it was designed in the first place) because it only accepts collections. What we really want is a Collection that offers an iterator that is safe to use (single-threadedly) while the collection is being modified. :TODO:
