Detailed Description

Interface that must be implemented in order to provide data updates to DataSource peers for cached objects. It contains callbacks that handle subscription and discard requests.

Note: the CachingDataProvider methods are not called on a dedicated worker thread. Therefore, if any of these methods are likely take a relatively long time to execute, they should be coded to run in a separate thread.
