7/// \ingroup basic
8/// \class AliMpDataStreams
9/// \brief Mapping data streams provider
10///
11/// The class provides input streams for mapping data;
12/// the input streams can be represented either by the
ab167304 13/// data files or by string streams filled from string map (AliMpDataMap).
14/// The string map is set from outside (AliMpCDB) and is not
15/// deleted in this class.
16/// The data streams returned by CreateDataStream() function
17/// must be deleted by the client code.
228fd720 18///
ab167304 19/// The selection between files and string streams is
20/// done in the constructor:
21/// if data map is provided, reading is performed from streams,
22/// otherwise reading is performed from file.
23/// User can also use the set function to select reading
24/// from files also when the data map is provided: \n
25/// void SetReadFromFiles();
