### Attach muxer to a transport ### Attach muxer to a transport
- `Node.js` muxer.attach(transport, function (err, conn)) - `Node.js` muxer.attach(transport, function (err, conn))
- `Go` conn, err := muxer.attach(transport) - `Go` conn, err := muxer.Attach(transport)
This method attaches our stream muxer to the desired transport (UDP, TCP) and returns/callbacks with the `err, conn`(error, connection).
If `err` is passed, no operation should be made in `conn`.
`conn` abstracts our established Connection with the other endpoint, it must offer an interface to open a stream inside this connection and to receive incomming stream requests.
### Dial(open/create) a new stream ### Dial(open/create) a new stream
- `Node.js` conn.dialStream(function (err, stream)) - `Node.js` conn.dialStream(function (err, stream))
- `Go` stream, err := conn.dialStream() - `Go` stream, err := conn.DialStream()
This method negotiates and opens a new stream with the other endpoint.
### Listen(wait/receive) a new incoming stream If `err` is passed, no operation should be made in `stream`.
`stream` abstract our established Stream with the other endpoint, it must implement the [Duplex Stream interface](https://nodejs.org/api/stream.html#stream_class_stream_duplex) in Node.js or the [ReadWriteCloser](http://golang.org/pkg/io/#ReadWriteCloser) in Go.
### Listen(wait/accept) a new incoming stream
- `Node.js` conn.on('stream', function (stream)) - `Node.js` conn.on('stream', function (stream))
- `Go` stream := conn.listen() - `Go` stream := conn.Accept()
Each time a dialing peer initiates the new stream handshake, a new stream is created on the listening side.
In Node.js, the Event Emitter pattern is expected to be used in order to receive new incoming streams, while in Go, it expects to wait when Accept is called.
