Member Function Documentation
QCanBusDeviceInfo::QCanBusDeviceInfo(const QCanBusDeviceInfo &other)
Constructs a copy of other.
QCanBusDeviceInfo &QCanBusDeviceInfo::operator=(QCanBusDeviceInfo &&other)
Move-assigns other to this QCanBusDeviceInfo instance.
QCanBusDeviceInfo &QCanBusDeviceInfo::operator=(const QCanBusDeviceInfo &other)
Assigns other to this CAN bus device info and returns a reference to this CAN bus device info.
QCanBusDeviceInfo::~QCanBusDeviceInfo()
Destroys the CAN bus device info.
int QCanBusDeviceInfo::channel() const
Returns the sequential channel number of the CAN bus interface, starting with zero. For example, a two channel CAN interface may have the channels 0 and 1. If the interface has only one channel or if no information about the channel is available, zero is returned.
This function was introduced in Qt 5.11.
QString QCanBusDeviceInfo::description() const
Returns a textual description of the CAN bus interface, if available. Example output: "PCAN USB Pro FD". If no description is available, an empty string is returned.
This function was introduced in Qt 5.11.
bool QCanBusDeviceInfo::hasFlexibleDataRate() const
Returns true, if the CAN bus interface is CAN FD (flexible data rate) capable.
If this information is not available, false is returned.
bool QCanBusDeviceInfo::isVirtual() const
Returns true, if the CAN bus interface is virtual (i.e. not connected to real CAN hardware).
If this information is not available, false is returned.
QString QCanBusDeviceInfo::name() const
Returns the interface name of this CAN bus interface, e.g. can0.
QString QCanBusDeviceInfo::serialNumber() const
Returns the serial number of the CAN bus interface as string, if available. Otherwise, an empty string is returned.
This function was introduced in Qt 5.11.
void QCanBusDeviceInfo::swap(QCanBusDeviceInfo &other)
Swaps this CAN bus device info with other. This operation is very fast and never fails.
