27 | /** | |
28 | * @class AliHLTReconstructor | |
29 | * AliHLTReconstructor AliRoot event reconstruction plugin for the HLT. | |
30 | * The AliHLTReconstructor holds an instance of the @ref AliHLTSystem | |
31 | * steering class. The actual reconstruction depends on the loaded component | |
32 | * libraries. Each library must implement a module agent (@ref AliHLTModuleAgent) | |
33 | * in order to provide information on the supported features and the | |
34 | * configurations to be run. | |
35 | * | |
36 | * The default component libraries which are loaded through the initialization | |
37 | * are determined by the @ref kHLTDefaultLibs array. The library loading can | |
38 | * be overridden by an option to the AliHLTReconstructor through the | |
39 | * <tt>SetOption</tt> method of <tt>AliReconstruction</tt>, e.g. | |
40 | * <pre> | |
41 | * AliReconstruction rec; | |
42 | * rec.SetOption("HLT", "libAliHLTSample.so"); | |
43 | * </pre> | |
44 | * will only load <tt>libAliHLTSample.so</tt> | |
45 | * | |
46 | * Optional arguments:<br> | |
47 | * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formating --> | |
48 | * \li loglevel=<i>level</i><br> | |
49 | * level can be a hex number encoding the @ref AliHLTComponentLogSeverity | |
50 | * \li alilog=off <br> | |
51 | * disables the logging of HLT log messages through <tt>AliLog</tt> <br> | |
52 | * | |
53 | * For further information on the AliRoot reconstruction refer to the AliRoot | |
54 | * documentation, namely <tt>AliReconstruction</tt>. | |
