Detailed Description

This class specifies the interface a backend will have to implement in order to be used in the system.

A device manager allows to query the underlying platform to discover the available devices. It has also the responsibility to notify when a device appears or disappears.

Member Function Documentation

allDevices()

virtual QStringList Solid::Ifaces::DeviceManager::allDevices ( )

pure virtual

Retrieves the Universal Device Identifier (UDI) of all the devices available in the system.

This identifier is unique for each device in the system.

Returns

the UDIs of all the devices in the system

Implemented in Solid::Backends::Fake::FakeManager.

createDevice()

virtual QObject * Solid::Ifaces::DeviceManager::createDevice ( const QString & udi )

pure virtual

Instantiates a new Device object from this backend given its UDI.

Parameters

udi	the identifier of the device instantiated

Returns

a new Device object if there's a device having the given UDI, 0 otherwise

Implemented in Solid::Backends::Fake::FakeManager.

deviceAdded

void Solid::Ifaces::DeviceManager::deviceAdded ( const QString & udi )

signal

This signal is emitted when a new device appears in the system.

Parameters

udi	the new device identifier

deviceRemoved

void Solid::Ifaces::DeviceManager::deviceRemoved ( const QString & udi )

signal

This signal is emitted when a device disappears from the system.

Parameters

udi	the old device identifier

devicesFromQuery()

virtual QStringList Solid::Ifaces::DeviceManager::devicesFromQuery ( const QString & parentUdi, Solid::DeviceInterface::Type type = Solid::DeviceInterface::Unknown )

pure virtual

Retrieves the Universal Device Identifier (UDI) of all the devices matching the given constraints (parent and device interface)

Parameters

parentUdi	UDI of the parent of the devices we're searching for, or QString() if there's no constraint on the parent
type	DeviceInterface type available on the devices we're looking for, or DeviceInterface::Unknown if there's no constraint on the device interfaces

Returns

the UDIs of all the devices having the given parent and device interface

Implemented in Solid::Backends::Fake::FakeManager.

supportedInterfaces()

virtual QSet< Solid::DeviceInterface::Type > Solid::Ifaces::DeviceManager::supportedInterfaces ( ) const

pure virtual

Retrieves a set of interfaces the backend supports.

Implemented in Solid::Backends::Fake::FakeManager.

udiPrefix()

virtual QString Solid::Ifaces::DeviceManager::udiPrefix ( ) const

pure virtual

Retrieves the prefix used for the UDIs off all the devices reported by the device manager.

Implemented in Solid::Backends::Fake::FakeManager.
