Each plugin may support one or more interfaces with different capabilities. This class provides information about available functions.

QString
QCanBusDeviceInfo::
alias
() const
Returns a user defineable alias associated with this CAN bus interface.
Some CAN bus interfaces can have a user defined alias associated. This is mostly done with the CAN hardware vendors tools. The alias allows to identify this hardware later, especially when multiple interfaces are connected.
注意: In contrast to serialNumber (), the alias is not guaranteed to be unique.
If this function is not supported by the CAN plugin, an empty string is returned.
该函数在 Qt 6.0 引入。
另请参阅 serialNumber ().
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.
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.
Returns true, if the CAN bus interface is CAN FD (flexible data rate) capable.
If this information is not available, false is returned.
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.
Returns the interface name of this CAN bus interface, e.g. "can0".
This corresponds to the
interfaceName
parameter of
QCanBus::createDevice
().
[since 6.2]
QString
QCanBusDeviceInfo::
plugin
() const
Returns the plugin name of this CAN bus interface, e.g. "peakcan".
This corresponds to the
plugin
parameter of
QCanBus::createDevice
().
该函数在 Qt 6.2 引入。
Returns the serial number of the CAN bus interface as string, if available. Otherwise, an empty string is returned.
另请参阅 alias ().
Swaps this CAN bus device info with other 。此操作非常快且从不失败。
赋值 other to this CAN bus device info and returns a reference to this CAN bus device info.
Move-assigns other to this QCanBusDeviceInfo 实例。
