COMMONSRDF-12 Graph.iterate() - don't extend Iterable
> Graph to be Iterable
> --------------------
>
> Key: COMMONSRDF-12
> URL: https://issues.apache.org/jira/browse/COMMONSRDF-12
> Project: Apache Commons RDF
> Issue Type: New Feature
> Reporter: Stian Soiland-Reyes
> Assignee: Stian Soiland-Reyes
>
> A Graph is a collection of triples, yet it does not support the Iterable
> interface, and thus can't be used in a classic for-each loop like:
> {code}
> for (Triple t : graph) {
> System.out.println(t);
> }
> {code}
> instead you are forced to use .getTriples() and either .sequential().forEach,
> or the awkward casting with ::iterator
> http://stackoverflow.com/questions/20129762/why-does-streamt-not-implement-iterablet
> Note that Stream is not Iterable, as it can only be iterated over once.. (I
> often find my self adding a function like iterable() to work around such
> cases).
> My proposal is simply to add the interface Iterable and have a default
> implementation that calls getTriples().iterator().
> It could be that there are other solutions that also work with the filtered
> getTriples() - e.g. some kind of Collector that is iterable?
