`time_zone`	`Any`	The data's time zone	required
`maximum_data_age`	`timedelta`	The maximum age of data allowed	required

current

current: BaseData

Gets the element in the collection at the current position of the enumerator.

dispose

dispose() -> None

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

move_next

move_next() -> bool

Advances the enumerator to the next element of the collection.

Returns:

Type	Description
