34 | * AliHLTMUONTriggerRecordsSource is a HLT-AliRoot data source object which generates | |
35 | * and serves AliHLTMUONTriggerRecordsBlockStruct type data blocks to the HLT system. | |
36 | * This is meant as a debugging utility which can optionally generate the data | |
37 | * blocks from simulated GEANT hits, simulated local trigger objects or MUON | |
38 | * offline reconstructed local trigger objects. | |
39 | * | |
40 | * Command line flags: | |
41 | * -hitdata | |
42 | * Specify this option to publish trigger records constructed from GEANT hits. | |
43 | * -simdata | |
44 | * Specify this option to publish trigger records constructed from simulated | |
45 | * local trigger objects. | |
46 | * -recdata | |
47 | * Specify this option to publish trigger records constructed from offline | |
48 | * reconstructed local trigger objects. | |
49 | * -plane left|right|all | |
50 | * Specifies if data from the left (x < 0), right (x >= 0) or the whole XY | |
51 | * plane should be published. | |
c06fe66f | 52 | * -firstevent <number> |
53 | * Indicates the first event number to fetch from AliRoot. The default is to | |
54 | * start from zero and increment the event number after every GetEvent call. | |
55 | * This mode causes the component to ignore the event number passed to it by | |
56 | * the system and rather use an internal counter. This mode can be overriden | |
57 | * with the -event_number_literal flag. | |
58 | * -event_number_literal | |
59 | * This flag indicates to use the event numbers as literal indices into the | |
60 | * AliRoot trees. This option will cause the component to ignore the -firstevent | |
61 | * flag. | |
