        Description:
        public abstract class MediaContainer : 
MediaObject
         
        
          This is a container (folder) for media items and child containers.
          It provides a basic serialization implementation (to DIDLLiteWriter).
          A derived class should provide a working implementation of get_children and should emit the container_updated signal.
          When used as a root container, you may wish to use the variables, such as REALNAME, in in the title. See the title property of the 
            #RygelMediaObject.
          If the container should support UPnP search operations then you also implement the #RygelSearchableContainer interface.
          If the container should be writable, meaning that it allows adding (via upload), removal and editing of items then you should also 
            implement the #RygelWritableContainer interface.
          If the container should support the change tracking profile of the UPnP ContentDirectory:3 specification then you should also implement 
            the #RygelTrackableContainer interface.
          The #RygelSimpleContainer class contains a simple memory-based container implementation, but most real-world uses will require custom 
            container implementations.

            Creation methods:
            
              - public MediaContainer (stringid, MediaContainer? parent,stringtitle,intchild_count)Create a media container with the specified details.
                 
- public MediaContainer.root (stringtitle,intchild_count)Create a root media container with the specified details, with no 
                    parent container, and with an appropriate ID.
                 
Methods:
            
              - public override void constructed ()
                
                
                 
- public abstract async MediaObjects? get_children (uintoffset,uintmax_count,stringsort_criteria,Cancellable? cancellable) throwsErrorFetches the list of media objects directly under this container.
                  
                 
- public abstract async MediaObject? find_object (stringid,Cancellable? cancellable) throwsErrorRecursively searches this container for a media object with the 
                    given ID.
                 
- public void updated (MediaObject? object = null, ObjectEventType event_type = MODIFIED, boolsub_tree_update = false)This method should be called each time this container is updated.
                  
                 
Signals:
            
              - public signal void container_updated (MediaContainer container, MediaObject object, ObjectEventType event_type, boolsub_tree_update)The container_updated signal is emitted if a child container under
                    the tree of this container has been updated. The object parameter is set to the MediaObject that is the source of the container 
                    update. Note that it may even be set to the container itself.
                 
- public signal void sub_tree_updates_finished (MediaObject sub_tree_root)
                
                The sub_tree_updates_finished signal is emitted when all of the 
                    sub-tree operations are finished. See the #RygelMediaContainer::container_updated signal.
