StreamSink<S> class abstract interface

A object that accepts stream events both synchronously and asynchronously.

A StreamSink combines the methods from StreamConsumer and EventSink.

The EventSink methods can't be used while the addStream is called. As soon as the addStream's Future completes with a value, the EventSink methods can be used again.

If addStream is called after any of the EventSink methods, it'll be delayed until the underlying system has consumed the data added by the EventSink methods.

When EventSink methods are used, the done Future can be used to catch any errors.

When close is called, it will return the done Future.
