Method Detail

handleFrames

public abstract HttpResponse handleFrames(org.apache.pekko.stream.Graph<org.apache.pekko.stream.FlowShape<FrameEvent,FrameEvent>,java.lang.Object> handlerFlow,
                                          scala.Option<java.lang.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.
