24 | // AliMDC // | |
25 | // // | |
26 | // Set of classes defining the ALICE RAW event format. The AliRawEvent // | |
27 | // class defines a RAW event. It consists of an AliEventHeader object // | |
28 | // an AliEquipmentHeader object, an AliRawData object and an array of // | |
29 | // sub-events, themselves also being AliRawEvents. The number of // | |
30 | // sub-events depends on the number of DATE LDC's. // | |
31 | // The AliRawEvent objects are written to a ROOT file using different // | |
32 | // technologies, i.e. to local disk via AliRawDB or via rfiod using // | |
33 | // AliRawRFIODB or via rootd using AliRawRootdDB or to CASTOR via // | |
34 | // rootd using AliRawCastorDB (and for performance testing there is // | |
35 | // also AliRawNullDB). // | |
a197a4ce | 36 | // The AliStats class provides statics information that is added as // |
37 | // a single keyed object to each raw file. // | |
38 | // The AliTagDB provides an interface to a TAG database. // | |
39 | // The AliMDC class is usid by the "alimdc" stand-alone program // | |
40 | // that reads data directly from DATE. // | |
