18 // The AliDAQ class is responsible for handling all the information about //
19 // Data Acquisition configuration. It defines the detector indexing, //
20 // the number of DDLs and LDCs per detector. //
21 // The number of LDCs per detector is used only in the simulation in order //
22 // to define the configuration of the dateStream application. Therefore the //
23 // numbers in the corresponding array can be changed without affecting the //
24 // rest of the aliroot code. //
25 // The equipment ID (DDL ID) is an integer (32-bit) number defined as: //
26 // Equipment ID = (detectorID << 8) + DDLIndex //
27 // where the detectorID is given by fgkDetectorName array and DDLIndex is //
28 // the index of the corresponding DDL inside the detector partition. //
29 // Due to DAQ/HLT limitations, the ddl indexes should be consequtive, or //
30 // at least without big gaps in between. //
31 // The sub-detector code use only this class in the simulation and reading //
32 // of the raw data. //
