21 | // | |
22 | // It loops over all PHOS/EMCAL digits in the raw data given by the AliRawReader. | |
23 | // The Next method goes to the next digit. If there are no digits left | |
24 | // it returns kFALSE. | |
25 | // Several getters provide information about the current digit. | |
26 | // usage: | |
27 | // AliRawReader *reader = AliRawReader::Create(fileName); | |
28 | // AliCaloRawStreamV3 *stream = new AliCaloRawStreamV3(reader,calo); | |
29 | // while (reader->NextEvent()) | |
30 | // while (stream->NextDDL()) | |
31 | // while (stream->NextChannel()) ... | |
