21// AliRawEvent //
22// //
23// Set of classes defining the ALICE RAW event format. The AliRawEvent //
24// class defines a RAW event. It consists of an AliEventHeader object //
25// an AliEquipmentHeader object, an AliRawData object and an array of //
26// sub-events, themselves also being AliRawEvents. The number of //
27// sub-events depends on the number of DATE LDC's. //
28// The AliRawEvent objects are written to a ROOT file using different //
29// technologies, i.e. to local disk via AliRawDB or via rfiod using //
30// AliRawRFIODB or via rootd using AliRawRootdDB or to CASTOR via //
31// rootd using AliRawCastorDB (and for performance testing there is //
32// also AliRawNullDB). //
33// The AliRunDB class provides the interface to the run and file //
34// catalogues (AliEn or plain MySQL). //
35// The AliStats class provides statics information that is added as //
36// a single keyed object to each raw file. //
37// The AliTagDB provides an interface to a TAG database. //
38// The AliMDC class is usid by the "alimdc" stand-alone program //
39// that reads data directly from DATE. //
