Class Mqtt5WebsocketHandshakeTransformArgs


  • public final class Mqtt5WebsocketHandshakeTransformArgs
    extends java.lang.Object
    Arguments to a websocket handshake transform operation. The transform may modify the http request before it is sent to the server. The transform MUST call complete() or completeExceptionally() when the transform is complete, failure to do so will stall the mqtt connection indefinitely. The transform operation may be asynchronous. The default websocket handshake http request uses path "/mqtt". All required headers for a websocket handshake are present, plus the optional header "Sec-WebSocket-Protocol: mqtt".
