Adam Jacobs commented on JENA-1427:
-----------------------------------
One more thought, rather than adding more functional methods to
{{ExtendedIterator}}, perhaps give it the ability to convert into a Java
{{Stream}}.
https://stackoverflow.com/questions/24511052/how-to-convert-an-iterator-to-a-stream
{noformat}
public default Stream<T> toStream() {
return StreamSupport.stream(Spliterators.spliteratorUnknownSize(this,
Spliterator.ORDERED), false);
}
{noformat}
Or give ExtendedIterator all of these methods! :)
> Add nextOrElse() method in ExtendedIterator
