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.
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.
