class sublime_music.adapters.filesystem.adapter.FilesystemAdapter(config, data_directory, is_cache=False)[source]

Bases: sublime_music.adapters.adapter_base.CachingAdapter

Defines an adapter which retrieves its data from the local filesystem.

Parameters

  • data_directory (pathlib.Path) – the directory where the adapter can store data. This directory is guaranteed to exist.

  • is_cache (bool) – whether or not the adapter is being used as a cache.

delete_data(key, param)[source]

This function will be called if the adapter should delete some of its data. This should destroy the data. If the deleted data is requested, a CacheMissError should be thrown with no data in the partial_data field.

Parameters

  • data_key – the type of data to be deleted.

  • params –

    the parameters that uniquely identify the data to be invalidated. For example, with playlist details, this will be the playlist ID.

    For the playlist list, this will be none since there are no parameters to that request.

  • key (sublime_music.adapters.adapter_base.CachingAdapter.CachedDataKey) –

  • param (Optional[str]) –

static get_configuration_form(config_store)[source]

This function should return a Gtk.Box that gets any inputs required from the user and uses the given config_store to store the configuration values.

The Gtk.Box must expose a signal with the name "config-valid-changed" which returns a single boolean value indicating whether or not the configuration is valid.

If you don’t want to implement all of the GTK logic yourself, and just want a simple form, then you can use the ConfigureServerForm class to generate a form in a declarative manner.

Return type

gi.overrides.Gtk.Box

Returns

The URI as a string.

Return type

str

get_directory(directory_id)[source]

Return a Directory object representing the song files and directories in the given directory. This may not make sense for your adapter (for example, if there’s no actual underlying filesystem). In that case, make sure to set can_get_directory to False.

Parameters

    For the playlist list, this will be none since there are no parameters to that request.

  • data (Any) – the data that was returned by the ground truth adapter.

initial_sync()[source]

Perform any operations that are required to get the adapter functioning properly. For example, this function can be used to wait for an initial ping to come back from the server.

invalidate_data(key, param)[source]

This function will be called if the adapter should invalidate some of its data. This should not destroy the invalidated data. If invalid data is requested, a CacheMissError should be thrown, but the old data should be included in the partial_data field of the error.

Parameters

  • data_key – the type of data to be invalidated.

  • params –

    the parameters that uniquely identify the data to be invalidated. For example, with playlist details, this will be the playlist ID.

    For the playlist list, this will be none since there are no parameters to that request.

  • key (sublime_music.adapters.adapter_base.CachingAdapter.CachedDataKey) –

  • param (Optional[str]) –

is_networked = False
static migrate_configuration(config_store)[source]
