I have a feeling I just lifted all the java doc from the underlying methods,
they may have changed in the last 5 years and I'll also incorporate your
suggestions. Regarding the constructors/factory methods, personally I would
prefer to replace the whole lot with a builder but that's obviously quite a
departure from the existing code, I had designed this PR to be as close as
possible to the existing but I'm happy to make it 'better' if it would be
accepted? ---- On Mon, 06 Sep 2021 19:40:47 +0100 ***@***.*** wrote ----

Confusing API name because it does not return a Path; either rename the API
or make it return a Path.

The name of... what? the base file name? The full file name?

There are way too many new factory APIs here IMO. For the first cut, let's
add one and see what other use-cases require in the future. If a delay is
provided, please make that a Duration, not a long. I'll redo the internals
after this PR comes in to use a Duration instead of a long. If you add a
constructor, make it private or package private.
