Grl.PluginDeinitFunc(plugin)

Parameters:

plugin (Grl.Plugin) –

Grl.PluginRegisterKeysFunc(registry, plugin)

Parameters:

• registry (Grl.Registry) –

• plugin (Grl.Plugin) –

Grl.SourceRemoveCb(source, media, user_data, error)

Parameters:

• source (Grl.Source) – a source

• media (Grl.Media) – a data transfer object

• user_data (object or None) – user data passed to Grl.Source.remove()

• error (GLib.Error or None) – possible GLib.Error generated at processing

Prototype for the callback passed to Grl.Source.remove()

Grl.SourceResolveCb(source, operation_id, media, user_data, error)

Parameters:

• source (Grl.Source) – a source

• operation_id (int) – operation identifier

• media (Grl.Media) – a data transfer object

• user_data (object or None) – user data passed to Grl.Source.resolve()

• error (GLib.Error or None) – possible GLib.Error generated at processing

Prototype for the callback passed to Grl.Source.resolve(). If the URI did not resolve to a valid media record, media will be None. If there was an error during resolution, error will be set.

If media is non-None, ownership of it is transferred to the callback, and it must be freed afterwards using GObject.Object.unref().

Grl.SourceResultCb(source, operation_id, media, remaining, user_data, error)

Parameters:

• source (Grl.Source) – a source

• operation_id (int) – operation identifier

• media (Grl.Media or None) – a data transfer object

• remaining (int) – the number of remaining Grl.Media to process, or Grl.SOURCE_REMAINING_UNKNOWN if it is unknown

• user_data (object or None) – user data passed to the used method

• error (GLib.Error or None) – possible GLib.Error generated at processing

Prototype for the callback passed to the media sources’ methods

Grl.SourceStoreCb(source, media, failed_keys, user_data, error)

Parameters:

• source (Grl.Source) – a source

• media (Grl.Media) – a Grl.Media transfer object

• failed_keys ([int]) – GLib.List of keys that could not be updated, if any

• user_data (object or None) – user data

• error (GLib.Error or None) – possible GLib.Error generated

Prototype for the callback passed to grl_source_store_foo functions
