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 AliStats class provides statics information that is added as //
34 : // a single keyed object to each raw file. //
35 : // The AliTagDB provides an interface to a TAG database. //
36 : // The AliMDC class is usid by the "alimdc" stand-alone program //
37 : // that reads data directly from DATE. //
