@Deprecated(since="4.1.0") public class IterationWrapper<E,X extends Exception> extends AbstractCloseableIteration<E,X>
Deprecated.Abstract superclass for Iterations that wrap other Iterations. The abstract class IterationWrapper itself provides default methods that forward method calls to the wrapped Iteration. Subclasses of IterationWrapper should override some of these methods and may also provide additional methods and fields.
