The .Set() Relationship in Function LiFiMacHelper::CreateAPMac

[PennyXQZ]

Hi Shakir,

Thank you for providing such a good LiFi module. However, I am confused by the following function. Could you please give a short explain about the ".Set()" relationship between the lifiMac, lifiMaclow, lifiChannel, lifiPhy, lifiDevice, and lifiApNode? Or, could you give me some advice to figure out the relationships, why they are required to be set for each other?

I look forward to hearing from you. Thanks a lot!

NetDeviceContainer LiFiMacHelper::CreateAPMac (Ptr<Node> node, ns3::Ptr<LiFiPhy> lifiPhy, Ptr<LiFiChannelHelper> channelHelper,Ptr<NetDevice> ccnetdevice)
{
    NS_LOG_FUNCTION (this);
    Ptr<PointToPointNetDevice> netdevice = ns3::DynamicCast<PointToPointNetDevice> (ccnetdevice);

    Ptr<LiFiApMac> app_mac = CreateObject<LiFiApMac> ();
    app_mac-> SetCCMacAddress (netdevice->GetAddress());
    NetDeviceContainer devices;
    Ptr<LiFiChannel> channel = channelHelper->GetChannel(node->GetId());
    lifiPhy->SetChannel(channel);
    //Ptr<TdmaCentralMac> mac = CreateObject<TdmaCentralMac> ();
    ns3::Ptr<LiFiNetDevice> device = CreateObject<LiFiNetDevice> ();
    app_mac->SetAddress (Mac48Address::Allocate ());
    lifiPhy->SetDevice(device);
    app_mac->SetNode(node);
    Ptr<LiFiMacLow> LiFiMacLow = app_mac->GetMacLow();
    lifiPhy->SetMacLow(LiFiMacLow);
    LiFiMacLow->SetPhy(lifiPhy);
    //device->SetMacHigh (app_mac);
    node->AddDevice (device);
    device->SetMac(app_mac);
    //app_mac->SetMac(mac);
    //app_mac->SetDevice(device);
    //app_mac->SetMacLow(LiFiMacLow);
    //mac->SetLiFiApMac(app_mac);
    m_remoteStationManager->AddMac(app_mac,app_mac->GetAddress());
    app_mac->SetRemoteStationManager(m_remoteStationManager);
    m_lifi_ap_netDevicesMap.insert (std::pair<uint32_t,Ptr<LiFiApMac> >(node->GetId(), app_mac)); 
    return NetDeviceContainer(device);
