GatewayInfo Event

Fired when the class receives a GWINFO or ADVERTISE packet.

Syntax

class MQTTSNGatewayInfoEventParams {
public:
  const QString &MessageType();
  int GatewayId();
  const QString &GatewayAddress();
  int Interval();
  int EventRetVal();
  void SetEventRetVal(int iRetVal);
};

// To handle, connect one or more slots to this signal.
void GatewayInfo(MQTTSNGatewayInfoEventParams *e);

// Or, subclass MQTTSN and override this emitter function.
virtual int FireGatewayInfo(MQTTSNGatewayInfoEventParams *e) {...}

Remarks

This event allows packets containing gateway information to be processed. These packets could be received from regular gateway advertisements or gateway info requests from this or other clients. This gateway information is used to manage the client's list of active gateways.

The value of MessageType could be GWINFO or ADVERTISE.

GatewayAddress will be in format host:port.

If the gateway address field is not present in the received GWINFO packet, GatewayAddress will use the packet source IP address.
