Return a list of containers. @return: A list of Container instances.
Return a container instance.
@type container_name: C{str}
@param container_name: Container name.
@return: C{Container} instance.
Create a new container.
@type container_name: C{str}
@param container_name: Container name.
@return: C{Container} instance on success.
Delete a container.
@type container: C{Container}
@param container: Container instance
@rtype: C{bool}
@return: True on success, False otherwise.
Return an object instance.
@type container_name: C{str}
@param container_name: Container name.
@type object_name: C{str}
@param object_name: Object name.
@return: C{Object} instance.
Upload an object currently located on a disk.
@type file_path: C{str}
@param file_path: Path to the object on disk.
@type container: C{Container}
@param container: Destination container.
@type object_name: C{str}
@param object_name: Object name.
@type extra: C{dict}
@param extra: (optional) Extra attributes (driver specific).
Upload an object using an iterator.
If a provider supports it, chunked transfer encoding is used and you
don't need to know in advance the amount of data to be uploaded.
Otherwise if a provider doesn't support it, iterator will be exhausted
so a total size for data to be uploaded can be determined.
Note: Exhausting the iterator means that the whole data must be buffered
in memory which might result in memory exhausting when uploading a very
large object.
If a file is located on a disk you are advised to use upload_object
function which uses fs.stat function to determine the file size and it
doesn't need to buffer whole object in the memory.
@type iterator: C{object}

a content type of the stored object.
