[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

重實現自 QCanBusFactory::createDevice ().

創建新的 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.

如果工廠不能創建插件，它返迴 nullptr .
