handleFrames

public abstract HttpResponse handleFrames(akka.stream.Graph<akka.stream.FlowShape<FrameEvent,FrameEvent>,Object> handlerFlow,
 scala.Option<String> subprotocol)

The low-level interface to create WebSocket server based on "frames". The user needs to handle control frames manually in this case.

Returns a response to return in a request handler that will signal the low-level HTTP implementation to upgrade the connection to WebSocket and use the supplied handler to handle incoming WebSocket frames.
