Ancestors

Instance methods

fu_backend_add_string

Add backend-specific device metadata to an existing string.

since: 1.8.4

fu_backend_coldplug

Adds devices using the subclassed backend. If fu_backend_setup() has not already been called then it is run before this function automatically.

since: 1.6.1

fu_backend_device_added

Emits a signal that indicates the device has been added.

since: 1.6.1

fu_backend_device_changed

Emits a signal that indicates the device has been changed.

since: 1.6.1

fu_backend_device_removed

Emits a signal that indicates the device has been removed.

since: 1.6.1

fu_backend_get_context

Gets the context for a backend.

since: 1.6.1

fu_backend_get_devices

Gets all the devices added by the backend.

since: 1.6.1

fu_backend_get_enabled

Return the boolean value of a key if it’s been configured.

since: 1.6.1

fu_backend_get_name

Return the name of the backend, which is normally set by the subclass.

since: 1.6.1

fu_backend_invalidate

Normally when calling fu_backend_setup() multiple times it is only actually done once. Calling this method causes the next requests to fu_backend_setup() to actually probe the hardware.

since: 1.8.0

fu_backend_load

Loads the backend from a JSON object.

since: 1.8.5

fu_backend_lookup_by_id

Gets a device previously added by the backend.

since: 1.6.1

fu_backend_registered

Calls the ->registered() vfunc for the backend. This allows the backend to perform shared backend actions on superclassed devices.

since: 1.7.4

fu_backend_save

Saves the backend to a JSON builder.

since: 1.8.5

fu_backend_set_enabled

Sets the backend enabled state.

since: 1.6.1

fu_backend_setup

Sets up the backend ready for use, which typically calls the subclassed setup function. No devices should be added or removed at this point.

since: 1.6.1

Signals

FwupdPlugin.Backend::device-added

The ::device-added signal is emitted when a device has been added.

since: 1.6.1

FwupdPlugin.Backend::device-changed

The ::device-changed signal is emitted when a device has been changed.

since: 1.6.1

FwupdPlugin.Backend::device-removed

The ::device-removed signal is emitted when a device has been removed.

since: 1.6.1

Signals inherited from GObject (1)
GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
