        Interfaces:
        
          - SearchableContainer - The base class for 
              searchable containers.
- TrackableContainer - The base class for 
              containers that provide automatic change tracking.
- TrackableItem
- VisualItem - An interface representing visual 
              properties of an item stored in a file.
- WritableContainer - This interface should 
              be implemented by 'writable' containers - ones that allow adding (via upload), removal and editing of items directly under them. 
              Currently, only addition and removal are supported.
- DataSource - Interface for all data streams 
              provided by a #RygelMediaEngine.
- UpdatableObject - This interface should be 
              implemented by 'updatable' objects - ones that allow modifying their own metadata in some persistent storage.
Classes:
        
          - AudioItem - Represents an audio item contained in a 
              file.
- ImageItem - Represents an image item.
- LogicalExpression - This is a parsed UPnP 
              search expression consisting of two other search expressions joined by a boolean operator such as AND or OR.
- MediaArtStore - This maps RygelMusicItem objects to
              their cached cover art, implementing the GNOME MediaArt storage 
                specification.
- MediaObjects - An array list that keeps media 
              objects.
- MusicItem - Represents a music item.
- PhotoItem - Represents a photo item.
- RelationalExpression - This is a parsed UPnP
              search expression consisting of two strings joined by a relational operator such as such <, <=, ==, !=, >, >=, derivedFrom 
              or exists.
- SimpleContainer - A simple implementation of 
              RygelMediaContainer that keeps all RygelMediaObjects in memory. You should add children via rygel_simple_container_add_child_item().
            
- Subtitle - Represents a subtitle for a video.
          
- Thumbnail - Represents a picture or video thumbnail.
            
- VideoItem - Represents a video item.
- MediaContainer - This is a container 
              (folder) for media items and child containers.
- MediaItem - Abstract class representing a 
              MediaItem
- MediaFileItem - Represents a file-
              accessible or http-accessible media item (music file, image file, video file, etc) with some pre-established metadata or a content 
              placeholder for uploaded content.
- MediaObject - Represents a media object 
              (container or item).
- MediaResource - Represents a media resource (Music,
              Video, Image, etc).
- MediaServerPlugin - This is the base 
              class for every Rygel implementation of a UPnP media server. It should be used either for a real plug-in for the Rygel process or used 
              in-process via the librygel-server API.
- SearchExpression - Represents a 
              SearchExpression tree.
- MediaServer - This class may be used to implement in-
              process UPnP-AV media servers.
- MediaEngine - This is the base class for 
              media engines that contain knowledge about the streaming and transformational capabilites of the media library in use.
- HTTPSeekRequest - HTTPSeekRequest is an 
              abstract base for a variety of seek request types.
- PlaylistItem - Represents a playlist item.
          
- ContentDirectory - Basic implementation of UPnP 
              ContentDirectory service version 2. Most often plugins will provide a child of this class. The inheriting classes should override 
              create_root_container method.
- HTTPByteSeekRequest
- HTTPByteSeekResponse
- HTTPGetHandler - HTTP GET request handler
              interface.
- HTTPGet - Responsible for handling HTTP GET & HEAD 
              client requests.
- HTTPItemURI
- HTTPRequest - Base class for HTTP client 
              requests.
- HTTPResponse
- HTTPResponseElement - This abstract 
              class represents an entity that can contribute response headers to a HTTP request.
- HTTPServer
- HTTPTimeSeekRequest - This class represents a
              DLNA TimeSeekRange request.
- HTTPTimeSeekResponse
- Serializer - Proxy class hiding the different 
              serializers (DIDL, DIDL_S, M3U) behind a single implementation.
- PlaySpeed - This is a container for a PlaySpeed value.
            
- PlaySpeedRequest - This class represents a DLNA 
              PlaySpeed request (PlaySpeed.dlna.org)
- PlaySpeedResponse - This class represents a 
              DLNA PlaySpeed response (PlaySpeed.dlna.org)
- DTCPCleartextRequest
- DTCPCleartextResponse
- DLNAAvailableSeekRangeRequest - 
              This class represents a DLNA getAvailableSeekRange request.
- DLNAAvailableSeekRangeResponse
