> Replace OutputTimeFn with enum

> Key: BEAM-1327
> URL: https://issues.apache.org/jira/browse/BEAM-1327
> Project: Beam
> Issue Type: New Feature
> Components: sdk-java-core
> Reporter: Kenneth Knowles
> Assignee: Kenneth Knowles
> Priority: Minor
> Labels: backward-incompatible
> Fix For: First stable release
>
>
> The class {{OutputTimeFn}} is overkill for a Fn API crossing. There are only
> three sensible values known: MIN, MAX, EOW. The interface is right for
> implementing these, but the full class is left over from the days when there
> was little cost to shipping new kinds of fns. An enum is concise.
> This can be done "mostly" backwards compatibly with legacy adapters in place,
> but might be less confusing without them.
