Writable stream API partially missing

[dcousens]

The following methods (from the stream.Writable interface) are not exposed on a through2 stream:

• cork
• uncork
• setDefaultEncoding

Given that through2 is just a wrapper around a Transform; and a Transform is just a Duplex stream. And a Duplex stream is a:

... stream that implement[s] both the Readable and Writable interfaces.

What am I missing?

through2 currently uses streams2 using the readable-stream module. the apis you are describing were added in streams3. i have an pr open for upgrading to streams3 (#46)

@mafintosh right! For some reason I thought the node docs were showing the streams 2 API. It'd be nice if the only version-like number they had on that page wasn't a 2.

Thanks @mafintosh.
