The QKnxNetIpSecuredServiceFamiliesDibProxy class provides the means to introspect the supported service families and required security version inside the generic QKnxNetIpDib class and to create a KNXnet/IP device information block (DIB) structure based on the information. 更多...

A KNXnet/IP secured service families DIB structure contains a set of supported services and their corresponding required security version. The service family is the high octet of the service type ID and the required security version is an integer representing the security version.
KNXnet/IP service families without security requirements will not be included in the secured service families DIB.
注意: When using QKnxNetIpSecuredServiceFamiliesDibProxy, care must be taken to ensure that the referenced KNXnet/IP DIB structure outlives the proxy on all code paths, lest the proxy ends up referencing deleted data.
Reading the secured service families can be achieved like this:
auto dib = QKnxNetIpDib::fromBytes(...); QKnxNetIpSecuredServiceFamiliesDibProxy proxy(dib); if (!proxy.isValid()) return; auto infos = proxy.serviceInfos();

Constructs a proxy object with the specified KNXnet/IP DIB structure dib to read the supported service families and security versions.

QKnxNetIpSecuredServiceFamiliesDibProxy::Builder
QKnxNetIpSecuredServiceFamiliesDibProxy::
builder
()
Returns a builder object to create a KNXnet/IP secured service families DIB structure.
Returns the description type of this KNXnet/IP structure if the object that was passed during construction was valid; otherwise returns QKnx::NetIp::Unknown .
返回
true
if the KNXnet/IP structure to create the object is a valid KNXnet/IP DIB structure; otherwise returns
false
.
Returns a vector of the QKnxSecuredServiceInfo carried by this KNXnet/IP DIB structure if the object that was passed during construction was valid; otherwise returns an empty vector.
