Method Details [hide private]

__init__(self)
(Constructor)

source code 
Lazily set name from class name styled with underscores (class ComponentBar -> name component_bar. Also set log category based on component name, with a 'comp_' prefix.
Overrides: core.component.Component.__init__
(inherited documentation)

scannable_uri_schemes__get(self)

source code 

Retrieve the URI schemes that can be scanned by the media_scanner. Since media scanning can be an heavy and long task the MediaProvider developer can choose to make the media_scanner skip URIs with scheme not appearing in returned list.

By default the return value of this method corresponds to the keys of supported_uri_schemes__get return value.

# FIXME: this should be documented in the class docstring as a class # variable
Overrides: base_components.media_provider.MediaProvider.scannable_uri_schemes__get
(inherited documentation)

supported_uri_schemes__get(self)

source code 

Retrieve the URI schemes supported by the provider, for each scheme there's a priority. Higher priority == 0 means the provider will always be used to read data from a given scheme.

This function is called by the MediaManager to know which media provider it has to use to access a specified URI. You should return a dict containing the uri scheme (such as 'file', 'cdda', ...) and its priority between 0 to 255 (0 being the topmost priority). The prority is used by the MediaManager to know which media provider it should use in case there are more than one who support the desired uri scheme. You might have for example a component which supports more than one scheme, but the support of one of them is not very efficient compared to what it could be. In this case you could modify its priority to tell the MediaManager that another component should be used instead of it to access this scheme.

example: { 'file': 0, 'smb': 10 }

# FIXME: this should be documented in the class docstring as a class # variable
Overrides: base_components.media_provider.MediaProvider.supported_uri_schemes__get
(inherited documentation)

_blocking_get_media_type(self, uri)

source code 
Try to guess the maximum information from the media located at given uri by looking at eventual file extension. Will return something like:
 {'file_type': string (values: one of media_provider.media_types)
  'mime_type': string (example: 'audio/mpeg' for .mp3 uris. can be
                      empty string if unguessable)
  }
'file_type' and 'mime_type' can be empty strings if it failed recognizing them.
Returns: dict
Overrides: base_components.media_provider.MediaProvider._blocking_get_media_type
(inherited documentation)

_blocking_is_directory(self, uri)

source code 
return True if a directory
Returns: bool
Overrides: base_components.media_provider.MediaProvider._blocking_is_directory
(inherited documentation)

_blocking_has_children_with_types(self, uri, media_types)

source code 
Detect whether the given uri has children for given media types which can be one of media_provider.media_types. Implies the URI is a directory as well.
Returns: bool
Overrides: base_components.media_provider.MediaProvider._blocking_has_children_with_types
(inherited documentation)

_blocking_get_direct_children(self, uri, children)

source code 

Scan the data located at given uri and return informations about its children. Fills children_with_info.

Typemap of filled result:
 [
    (uri : media_uri.MediaUri,
     additional info: dict),
   ...
 ]
If you supply additional info, they should be stored in a elisa.core.observers.dict.DictObservable instead of a normal dictionnary. Valid keys:
 ['default_image', 'artist', 'album', 'song', 'song_artist',
  'song_album']
Returns: list
Overrides: base_components.media_provider.MediaProvider._blocking_get_direct_children
(inherited documentation)

get_real_uri(self, uri)

source code 
Returns the original uri (acesable) from a virtual uri representation.
Returns: elisa.core.media_uri.MediaUri
Overrides: base_components.media_provider.MediaProvider.get_real_uri
(inherited documentation)
