成员函数
[pure virtual] QList<QCanBusDeviceInfo> QCanBusFactoryV2::availableDevices(QString *errorMessage) const
Returns the list of available devices and their capabilities for the QCanBusDevice.
errorMessage contains an error description in case of failure.
[pure virtual] QCanBusDevice *QCanBusFactoryV2::createDevice(const QString &interfaceName, QString *errorMessage) const
Reimplemented from QCanBusFactory::createDevice().
Creates a new QCanBusDevice. The caller must take ownership of the returned pointer.
interfaceName is the CAN interface name and errorMessage contains an error description in case of failure.
If the factory cannot create a plugin, it returns nullptr.
