12// AliRawEvent //
13// //
14// Set of classes defining the ALICE RAW event format. The AliRawEvent //
15// class defines a RAW event. It consists of an AliEventHeader object //
16// an AliEquipmentHeader object, an AliRawData object and an array of //
17// sub-events, themselves also being AliRawEvents. The number of //
18// sub-events depends on the number of DATE LDC's. //
19// The AliRawEvent objects are written to a ROOT file using different //
20// technologies, i.e. to local disk via AliRawDB or via rfiod using //
21// AliRawRFIODB or via rootd using AliRawRootdDB or to CASTOR via //
22// rootd using AliRawCastorDB (and for performance testing there is //
23// also AliRawNullDB). //
24// The AliRunDB class provides the interface to the run and file //
25// catalogues (AliEn or plain MySQL). //
26// The AliStats class provides statics information that is added as //
27// a single keyed object to each raw file. //
28// The AliTagDB provides an interface to a TAG database. //
29// The AliMDC class is usid by the "alimdc" stand-alone program //
30// that reads data directly from DATE. //
