public interface HistoricalTagValue
extends TagValue, HistoricalData
This interface defines a piece of history coming from a tag, and is used by the history storage system. It is a
TagValue, and adds on some information about the source and settings.
NOTE: The tag history system does not expect multiple values for a given path for a given time. It relies on
implementors of this interface to implement .equals() correctly in order to ensure this.
