A. Soroka commented on JENA-966:
--------------------------------
[~claudenw], would it be useful to you for me to send a PR showing my proposal
(adding {{andThen(Supplier<Iterator<T>>)}} to {{ExtendedIterator}}? It would
look something like:
{code}
ExtendedIterator andThen(final Supplier<Iterator<T>> nextIterator) {
return andThen(new Iterator<T>() {
public T next() { return nextIterator.get().next(); }
public boolean hasNext() { return nextIterator.get().hasNext(); }
public void remove() { nextIterator.get().remove); }
} );
}
{code}
and you would invoke it like {{ExtendedIterator joined = first.andThen(() ->
second);}}.

> Key: JENA-966
> URL: https://issues.apache.org/jira/browse/JENA-966
> Project: Apache Jena
> Issue Type: Bug
> Components: Core
> Affects Versions: Jena 3.0.0
> Reporter: Claude Warren
> Assignee: Claude Warren
>
> LazyIterator is an abstract class. The documentation indicates that the
> create() method needs to be overridden to create an instance. From this I
> would expect that
> now LazyIterator(){
> @Override
> public ExtendedIterator<Model> create() {
> ...
> }};
> Would work however LazyIterator does not override:
> remoteNext(), andThen(), toList(), and toSet().
> I believe these should be implemented in the class.
