Detailed Description

Mapping data streams provider.

The class provides input streams for mapping data; the input streams can be represented either by the data files or by string streams filled from string map (AliMpDataMap). The string map is set from outside (AliMpCDB) and is not deleted in this class. The data streams returned by CreateDataStream() function must be deleted by the client code.

The selection between files and string streams is done in the constructor: if data map is provided, reading is performed from streams, otherwise reading is performed from file. User can also use the set function to select reading from files also when the data map is provided:
void SetReadFromFiles();

Member Function Documentation

istream & AliMpDataStreams::CreateDataStream ( const TString & path ) const

Return the string with data in the mapping file spcified with path. Both full path in the file system and a short path (without $LICE_ROOT/mapping/data string) can be used.

void AliMpDataStreams::CutDataPath ( string & dataPath ) const

private

Cut the path defined in AliMpFiles as Top() + one more directory
