Interface CloseableIterator<E>

All Superinterfaces:
AutoCloseable, Iterator<E>
All Known Implementing Classes:
CloseableSuppliedIterator, ConcatIterator, FilterIterator, IteratorMapper, LazyConcatIterator, RemovableCloseableIterator, RemovableCloseableIterator, ScrollerIteratorAdaptor

public interface CloseableIterator<E> extends AutoCloseable, Iterator<E>
Interface that provides semantics of a Iterator and AutoCloseable interfaces. This is useful when you have data that must be iterated on and may hold resources in the underlying implementation that must be closed.

Some implementations may close resources automatically when the iterator is finished being iterated on however this is an implementation detail and all callers should call AutoCloseable.close() method to be sure all resources are freed properly.
