19 | Default ctor cannot create new objects, create dummy default ctor which leaves object in not well defined state - to be used only by root for I/O | |
20 | ||
314558d7 | 21 | Revision 1.10 2001/11/15 11:07:25 jchudoba |
22 | Set to zero new pointers to TPC and TRD special trees in the default ctor. Add const to all Get functions. Remove unused constant, rename constant according coding rules. | |
23 | ||
9ae76683 | 24 | Revision 1.9 2001/11/15 09:00:11 jchudoba |
25 | Add special treatment for TPC and TRD, they use different trees than other detectors | |

51 | // Manager object for merging/digitization | |
52 | // | |
53 | // Instance of this class manages the digitization and/or merging of | |
54 | // Sdigits into Digits. | |
55 | // | |
56 | // Only one instance of this class is created in the macro: | |
a90ecf3c | 57 | // AliRunDigitizer * manager = |
58 | // new AliRunDigitizer(nInputStreams,SPERB); | |
59 | // where nInputStreams is number of input streams and SPERB is | |
60 | // signals per background variable, which determines how combinations | |
61 | // of signal and background events are generated. | |
9ce40367 | 62 | // Then instances of specific detector digitizers are created: |
63 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager) | |
a90ecf3c | 64 | // and the I/O configured (you have to specify input files |
65 | // and an output file). The manager connects appropriate trees from | |
66 | // the input files according a combination returned by AliMergeCombi | |
9ae76683 | 67 | // class. It creates TreeD in the output and runs once per |
a90ecf3c | 68 | // event Digitize method of all existing AliDetDigitizers |
69 | // (without any option). AliDetDigitizers ask manager | |
70 | // for a TTree with input (manager->GetInputTreeS(Int_t i), | |
9ce40367 | 71 | // merge all inputs, digitize it, and save it in the TreeD |
72 | // obtained by manager->GetTreeD(). Output events are stored with | |
73 | // numbers from 0, this default can be changed by | |
74 | // manager->SetFirstOutputEventNr(Int_t) method. The particle numbers | |
75 | // in the output are shifted by MASK, which is taken from manager. | |
76 | // | |
8d5e6345 | 77 | // The default output is to the signal file (stream 0). This can be |
78 | // changed with the SetOutputFile(TString fn) method. | |
79 | // | |
9ae76683 | 80 | // Single input file is permitted. Maximum kMaxStreamsToMerge can be merged. |
9ce40367 | 81 | // Input from the memory (on-the-fly merging) is not yet |
82 | // supported, as well as access to the input data by invoking methods | |
83 | // on the output data. | |
84 | // | |
a90ecf3c | 85 | // Access to the some data is via gAlice for now (supposing the |
86 | // same geometry in all input files), gAlice is taken from the first | |
87 | // input file on the first stream. | |
9ce40367 | 88 | // |
314558d7 | 89 | // Example with MUON digitizer, no merging, just digitization |
90 | // | |
91 | // AliRunDigitizer * manager = new AliRunDigitizer(1,1); | |
92 | // manager->SetInputStream(0,"galice.root"); | |
93 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
94 | // manager->Exec(""); | |
95 | // | |
96 | // Example with MUON digitizer, merge all events from | |
97 | // galice.root (signal) file with events from bgr.root | |
98 | // (background) file. Number of merged events is | |
99 | // min(number of events in galice.root, number of events in bgr.root) | |
100 | // | |
101 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); | |
102 | // manager->SetInputStream(0,"galice.root"); | |
103 | // manager->SetInputStream(1,"bgr.root"); | |
104 | // AliMUONDigitizer *dMUON = new AliMUONDigitizer(manager); | |
105 | // manager->Exec(""); | |
106 | // | |
107 | // Example with MUON digitizer, save digits in a new file digits.root, | |
108 | // process only 1 event | |
9ce40367 | 109 | // |
a90ecf3c | 110 | // AliRunDigitizer * manager = new AliRunDigitizer(2,1); |
314558d7 | 111 | // manager->SetInputStream(0,"galice.root"); |
112 | // manager->SetInputStream(1,"bgr.root"); | |
