---------------------------------------------------------
Just as a sidenote for anyone following this who is not familiar with the use
of {{Supplier}}: {{Supplier}} is not part of the Java 8 Stream API, it's part
of the Function API. It is a very simple SAM interface that is intended to hold
a computation. So one might do:
{code:language=java}
# the only cost of the line below is an assignment
Supplier<Foo> fooForLater = () -> expensiveCompution();
# do some other stuff
# the line below is where we pay the cost of expensiveCompution()
Foo myFoo = fooForLater.get();
{code}

> 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.
