Interface TagHistoryProvider

All Superinterfaces:

AnnotationQueryProvider, TagHistoryQueryInterface

public interface TagHistoryProvider
extends TagHistoryQueryInterface

A TagHistoryProvider is a entity that provides, for querying, historical tag information. This is the main interface for any system that wishes to provide tag history. It does not, however, define functions for storing history. If a single system wishes to both store and provide history, it should also implement the DataSink interface and register it with the HistoryManager. The DataSink should accept the HistoryFlavor.SQLTAG type.
