    end

class EchoListenNotify is WebSocketListenNotify
  // A tcp connection connected, return a WebsocketConnectionNotify instance
  fun ref connected(): EchoConnectionNotify iso^ =>
    EchoConnectionNotify

class EchoConnectionNotify is WebSocketConnectionNotify
  // A websocket connection enters the OPEN state
  fun ref opened(conn: WebSocketConnection ref) =>
    @printf[I32]("New client connected\n".cstring())

  // UTF-8 text data received
  fun ref text_received(conn: WebSocketConnection ref, text: String) =>
    // Send the text back
    conn.send_text(text)

  // Binary data received
  fun ref binary_received(conn: WebSocketConnection ref, data: Array[U8] val) =>
    conn.send_binary(data)
