Detailed Description
Device stores a reference to device data provided by the backend. Device objects are designed to be used by value. Copying these objects is quite cheap, so using pointers to the me is generally not needed.
Member Function Documentation
[explicit]
Device::Device(const QString &udi = QString())
Constructs a device for a given Universal Device Identifier (UDI).
udi the udi of the device to create
[static]
QList<Solid::Device> Device::allDevices()
Retrieves all the devices available in the underlying system.
Returns the list of the devices available
template <typename DevIface> DevIface *Device::as()
Retrieves a specialized interface to interact with the device corresponding to a given device interface.
Returns a pointer to the device interface if it exists, 0 otherwise
template <typename DevIface> const DevIface *Device::as() const
Retrieves a specialized interface to interact with the device corresponding to a given device interface.
Returns a pointer to the device interface if it exists, 0 otherwise
Solid::DeviceInterface *Device::asDeviceInterface(const Solid::DeviceInterface::Type &type)
Retrieves a specialized interface to interact with the device corresponding to a particular device interface.
type the device interface type
Returns a pointer to the device interface interface if it exists, 0 otherwise
const Solid::DeviceInterface *Device::asDeviceInterface(const Solid::DeviceInterface::Type &type) const
Retrieves a specialized interface to interact with the device corresponding to a particular device interface.
type the device interface type
Returns a pointer to the device interface interface if it exists, 0 otherwise
[since 4.4]
QString Device::description() const
Retrieves the description of device.
Returns the description
This function was introduced in 4.4.
[since 5.71]
QString Device::displayName() const
Retrieves the display Name to use for this device. Same as description when not defined.
Returns the display Name
This function was introduced in 5.71.
[since 4.4]
QStringList Device::emblems() const
Retrieves the names of the emblems representing the state of this device. The naming follows the freedesktop.org specification.
Returns the emblem names
This function was introduced in 4.4.
QString Device::icon() const
Retrieves the name of the icon representing this device. The naming follows the freedesktop.org specification.
Returns the icon name
template <typename DevIface> bool Device::is() const
Tests if a device provides a given device interface.
Returns true if the interface is available, false otherwise
bool Device::isDeviceInterface(const Solid::DeviceInterface::Type &type) const
Tests if a device interface is available from the device.
type the device interface type to query
Returns true if the device interface is available, false otherwise
bool Device::isValid() const
Indicates if this device is valid.
A device is considered valid if it's available in the system.
Returns true
if this device is available, false
otherwise
[static]
QList<Solid::Device> Device::listFromQuery(const QString &predicate, const QString &parentUdi = QString())
Convenience function see above.
Returns the list of devices
[static]
QList<Solid::Device> Device::listFromQuery(const Solid::Predicate &predicate, const QString &parentUdi = QString())
Retrieves a list of devices of the system given matching the given constraints (parent and predicate)
predicate Predicate that the devices we're searching for must verify
parentUdi UDI of the parent of the devices we're searching for, or QString() if there's no constraint on the parent
Returns the list of devices corresponding to the given constraints
See also Solid::Predicate.
[static]
QList<Solid::Device> Device::listFromType(const Solid::DeviceInterface::Type &type, const QString &parentUdi = QString())
Retrieves a list of devices of the system given matching the given constraints (parent and device interface type)
type device interface type available on the devices we're looking for, or DeviceInterface::Unknown if there's no constraint on the device interfaces
parentUdi UDI of the parent of the devices we're searching for, or QString() if there's no constraint on the parent
Returns the list of devices corresponding to the given constraints
See also Solid::Predicate.
Solid::Device Device::parent() const
Retrieves the parent of the Device.
Returns the device's parent
See also parentUdi().
QString Device::parentUdi() const
Retrieves the Universal Device Identifier (UDI) of the Device's parent.
Returns the udi of the device's parent
QString Device::product() const
Retrieves the name of the product corresponding to this device.
Returns the product name
[static, since 5.73]
Solid::Device Device::storageAccessFromPath(const QString &path)
Returns the Device containing the filesystem for the given path
canonical path to a filesystem entry, e.g. a file or directory
Returns a Device containing the given path.
For Devices implementing the StorageVolume interface only ones matching UsageType::FileSystem are returned, i.e. no backing encrypted volumes.
This function was introduced in 5.73.
See also QFileInfo::canonicalFilePath.
QString Device::udi() const
Retrieves the Universal Device Identifier (UDI).
Warning: Don't use the UDI for anything except communication with Solid. Also don't store UDIs as there's no guarantee that the UDI stays the same when the hardware setup changed. The UDI is a unique identifier that is local to the computer in question and for the current boot session. The UDIs may change after a reboot. Similar hardware in other computers may have different values; different hardware could have the same UDI.
Returns the udi of the device
QString Device::vendor() const
Retrieves the name of the device vendor.
Returns the vendor name
