25 * @brief Class for generating reconstructed hits data blocks from AliRoot data.

34 * AliHLTMUONRecHitsSource is a HLT-AliRoot data source object which generates
35 * and serves AliHLTMUONRecHitsBlockStruct 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 or MUON offline reconstructed hits.
41 * Specify this option to publish GEANT hits.
43 * Specify this option to publish offline reconstructed raw clusters.
44 * -plane left|right|all
45 * Specifies if data from the left (x < 0), right (x >= 0) or the whole XY
46 * plane should be published.
47 * -chamber <number>|<number>-<number>[,<number>|<number>-<number>]...
48 * Selects the chambers from which to publish data. Valid chamber numbers
49 * in the range [1..10]. The string after '-chamber' is a comma separated
50 * list of numbers or ranges. Some examples of strings:
51 * 1 1-2 1,2,3 1,3-5,7 etc...
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
