詳細描述

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

QCanBusDeviceInfo:: QCanBusDeviceInfo (const QCanBusDeviceInfo & other )

構造副本為 other .

`[noexcept]` QCanBusDeviceInfo:: ~QCanBusDeviceInfo ()

銷毀 CAN 總綫設備信息。

`[since 6.0]` 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.

該函數在 Qt 6.0 引入。

另請參閱 serialNumber ().

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.

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.

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".

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 ().

該函數在 Qt 6.2 引入。

QString QCanBusDeviceInfo:: serialNumber () const

Returns the serial number of the CAN bus interface as string, if available. Otherwise, an empty string is returned.

另請參閱 alias ().

`[noexcept]` void QCanBusDeviceInfo:: swap ( QCanBusDeviceInfo & other )

Swaps this CAN bus device info with other 。此操作很快且從不失敗。

`[noexcept]` QCanBusDeviceInfo &QCanBusDeviceInfo:: operator= ( QCanBusDeviceInfo && other )

移動賦值 other 到此 QCanBusDeviceInfo 實例。

QCanBusDeviceInfo &QCanBusDeviceInfo:: operator= (const QCanBusDeviceInfo & other )

賦值 other to this CAN bus device info and returns a reference to this CAN bus device info.
