Detailed Description

This class allows applications to deal with devices available in the underlying system.

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.

udi()

QString Solid::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

Definition at line 68 of file frontend/device.cpp.

vendor()

QString Solid::Device::vendor

(

)

const

Retrieves the name of the device vendor.

Returns

the vendor name

Definition at line 89 of file frontend/device.cpp.
