The QKnxNetIpTunnelingInfoDibProxy class provides the means to read the maximum ADPU length supported by a KNXnet/IP tunneling interface and tunneling slot information from the generic QKnxNetIpDib class and to create a KNXnet/IP tunneling information block (DIB) structure. More...

This class was introduced in Qt 5.12.
|QKnxNetIpTunnelingInfoDibProxy(const QKnxNetIpDib &dib)|
If a KNXnet/IP server supports tunneling, it can send more detailed information about the supported tunnel connections. The tunneling slot info class can be used to represent this information. Usually it includes the individual addresses used for the connection once it has been established and whether the connection slot is available at all.
Note: When using QKnxNetIpTunnelingInfoDibProxy, 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 application layer protocol data unit (APDU) length and default tunneling slot information can be achieved like this:
Member Function Documentation
QKnxNetIpTunnelingInfoDibProxy::QKnxNetIpTunnelingInfoDibProxy(const QKnxNetIpDib &dib)
Constructs a proxy object with the specified KNXnet/IP DIB structure dib to read the maximum APDU length and tunneling slot information.
[static] QKnxNetIpTunnelingInfoDibProxy::Builder QKnxNetIpTunnelingInfoDibProxy::builder()
Returns a builder object to create a KNXnet/IP tunneling info 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.
true if the KNXnet/IP structure to create the object is a valid KNXnet/IP DIB structure; otherwise returns
A KNXnet/IP tunneling information DIB structure is considered valid if it contains the maximum APDU length and at least one tunneling slot information object.
quint16 QKnxNetIpTunnelingInfoDibProxy::maximumInterfaceApduLength() const
Returns the maximum APDU length carried by this KNXnet/IP DIB structure.
Note: If the object passed during construction was invalid, the function returns a default-constructed value which can be
See also isValid().
QVector<QKnxNetIpTunnelingSlotInfo> QKnxNetIpTunnelingInfoDibProxy::optionalSlotInfos() const
Returns a vector of QKnxNetIpTunnelingSlotInfo objects carried by this KNXnet/IP DIB structure if the object that was passed during construction was valid; otherwise returns an empty vector.
QKnxNetIpTunnelingSlotInfo QKnxNetIpTunnelingInfoDibProxy::tunnelingSlotInfo() const
Returns the mandatory tunneling slot information carried by this KNXnet/IP DIB structure or a default-constructed value in case of an error.
