Detailed Description

Data service base class.

A data service manages the transient data stores and implements the IDataProviderSvc and IDataManagerSvc interfaces.

The accessor methods are protected with a lock. This is done having in mind the DetDataSvc and the retrieval of subdetectors in a multithreaded FW. This solution cannot solve the problem of having different conditions set available simultaneously but it is the simplest solution to allow multiple algorithms running concurrently to access detector components. In first approximation, since for the data we have the whiteboard, we protect only the retrieval of objects.
