StreamCallback

trait StreamCallback extends AnyRef

Callback for streaming data. Stream data will be offered to the ByteBuffer) method as it arrives. Once all the stream data is received, #onComplete(String) will be called.

The network library guarantees that a single thread will call these methods at a time, but different call may be made by different threads.
