A DBus container should be used to dynamically publish Publishable objects within the same namespace. It generates a unique DBus path for each object. It is able to resolve a DBus path into an object and an object into a DBus path. Example: .. code-block:: python # Create a container of tasks. container = DBusContainer( namespace=("my", "project"), basename="Task", message_bus=DBus ) # Publish a task. path = container.to_object_path(MyTask()) # Resolve an object path into a task. task = container.from_object_path(path) Nc�����������������C���sH���||�_�|rg�|�|�R�}|dd��|�_|d�|�_i�|�_t��|�_d|�_dS�)z�Create a new container. :param message_bus: a message bus :param namespace: a sequence of names :param basename: a string with the base name N���r���)� _message_bus� _namespace� _basename� _container�set� _published�_counter)�selfZ message_bus� namespace�basenamer ���r ���r ����__init__?���s���� zDBusContainer.__init__c�����������������C���s ���||�_�dS�)z�Set the namespace.
