Marko A. Rodriguez commented on TINKERPOP3-790:
-----------------------------------------------
I can easily make {{TraversalSource}} extend {{AutoCloseable}}. The question
is, how would you update (lets say) {{GraphTravesalSource}} to clean up
{{EventStrategy}} stuff? Seems we would need strategies to also be able to
implement {{AutoCloseable}} and if so, on {{TraversalSource.close()}} loop
through strategies and if they can be closed (close them). Thoughts?

> A {{TraversalSource}} may have resources to release so having a {{close}}
> method would allows that release to occur. The specific case has to do with
> {{EventStrategy}} which registers a listener on {{Transaction}}. That
> listener should be removed when the user is done with the
> {{TraversalSource}}, but there is currently no way to clean that up. The
> calling of {{close}} should prevent future traversals from that
> {{TraversalSource}}.
> I suppose this also means that a {{TraversalStrategy}} will need to
> optionally implement {{AutoCloseable}} or some other marker interface to
> designate it as a strategy that needs to release resources.
