Class IterationSpliterator<T>

java.lang.Object

java.util.Spliterators.AbstractSpliterator<T>

org.eclipse.rdf4j.common.iteration.IterationSpliterator<T>

All Implemented Interfaces:

Spliterator<T>

public class IterationSpliterator<T>
extends Spliterators.AbstractSpliterator<T>

A Spliterator implementation that wraps an Iteration. It handles occurrence of checked exceptions by wrapping them in RuntimeExceptions, and in addition ensures that the wrapped Iteration is closed when exhausted (if it's a CloseableIteration).

Parameters:

iteration - the iteration to wrap
