Class ConcatIterator<E>

  • All Implemented Interfaces:
    AutoCloseable, Iterator<E>, CloseableIterator<E>

    public class ConcatIterator<E>
    extends AbstractIterator<E>
    implements CloseableIterator<E>
    Iterator that concatenates a bunch of iterables into 1 big iterator. Each iterable is retrieved lazily as requested. Note that if any of the produced iterators from the iterable implement CloseableIterator they will be closed when iterated upon fully or the last used iterator will be close when this iterator this closed.

    Removal is implemented and will invoke remove on the last used iterator
