okay, that was easy enough, whats next?
|
|
|
|
say, after you call paused(), write should return false
|
|
until resume is called.
|
|
|
|
simple way to implement this:
|
|
write must return !paused
|
|
after pause() paused = true
|
|
after resume() paused = false
|
|
|
|
on resume, if !paused drain is emitted again.
|
|
after drain, !paused
|
|
|
|
there are lots of subtle ordering bugs in streams.
|
|
|
|
example, set !paused before emitting drain.
|
|
|
|
the stream api is stateful.
