Builder Classclass QKnxNetIpSearchRequestProxy::Builder
The QKnxNetIpSearchRequestProxy::Builder class provides the means to create a KNXnet/IP search request. More...
|Builder &||setDiscoveryEndpoint(const QKnxNetIpHpai &hpai)|
To discover KNXnet/IP servers, a KNXnet/IP client sends a search request data packet via multicast using its discovery endpoint. The search request contains the host address protocol information (HPAI) of the discovery endpoint. The HPAI may also contain a unicast IP address to receive the answers from the different servers directly in a point-to-point manner. Typically, it should contain the KNXnet/IP system setup multicast address to ensure reception from KNXnet/IP servers that are on a different subnetwork.
In most programs, this class will not be used directly. Instead, the QKnxNetIpServerDiscoveryAgent and QKnxNetIpServerInfo are provided to discover KNXnet/IP servers on the network.
The common way to create a search request is:
auto hpai = QKnxNetIpHpaiProxy::builder().create(); auto netIpFrame = QKnxNetIpSearchRequestProxy::builder() .setDiscoveryEndpoint(hpai) .create();
After sending the search request, the KNXnet/IP client waits until timeout for the response frame from the KNXnet/IP server, QKnxNetIpSearchResponseProxy. After the timeout, received response frames are ignored by the client until it sends another search request. Search requests received from other clients are always ignored.

QKnxNetIpFrame Builder::create() const
Creates and returns a KNXnet/IP search request frame.
Note: The returned frame may be invalid depending on the values used during setup.

Builder &Builder::setDiscoveryEndpoint(const QKnxNetIpHpai &hpai)
Sets the discovery endpoint of the KNXnet/IP client to hpai and returns a reference to the builder.
