18 * @class AliHLTTriggerBarrelGeomMultiplicity
19 * HLT trigger component for charged particle multiplicity in the
20 * central barrel.
21 *
c308d915 22 * Triggers on charged particle number in a certain geometrical acceptance
46906312 23 *
24 * <h2>General properties:</h2>
25 *
26 * Component ID: \b BarrelGeomMultiplicityTrigger <br>
27 * Library: \b libAliHLTTrigger.so <br>
28 * Input Data Types: kAliHLTDataTypeESDObject, kAliHLTDataTypeESDTree
29 * kAliHLTDataTypeTrack <br>
30 * Output Data Types: ::kAliHLTAnyDataType <br>
31 *
32 * <h2>Mandatory arguments:</h2>
33 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
c308d915 34 * \li -triggername <i> n </i> <br>
35 * specifies which configuration object to use for the trigger
46906312 36 *
37 * <h2>Optional arguments:</h2>
38 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
c308d915 39 * \li -geomfile <i> n </i> <br>
40 * specifies root file containing configuration objects

42 * <h2>Configuration:</h2>
43 * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting -->
44 * \li -mintracks <i> n </i> <br>
45 * required number of tracks for a trigger
46906312 46 * \li -solenoidBz <i> field </i> <br>
47 * magnetic field needed if the input is not an ESD object
48 *
49 * By default, configuration is loaded from OCDB, can be overridden by
50 * component arguments.
51 *
52 * <h2>Default CDB entries:</h2>
c308d915 53 * HLT/ConfigHLT/BarrelGeomMultiplicityTrigger/<triggername>: TObjArray storing the
54 * geometries and readout parameters.
46906312 55 * HLT/ConfigHLT/Solenoidbz: TObjString -solenoidBz field
