18 | * @class AliHLTTriggerITSMultiplicity | |
19 | * HLT trigger component for cluster multiplicity in ITS. | |
20 | * | |
21 | * Triggers if number of clusters if over the set limit. | |
22 | * | |
23 | * <h2>General properties:</h2> | |
24 | * | |
25 | * Component ID: \b ITSMultiplicityTrigger <br> | |
26 | * Library: \b libAliHLTTrigger.so <br> | |
27 | * Input Data Types: kAliHLTDataTypeClusters <br> | |
28 | * Output Data Types: ::kAliHLTAnyDataType <br> | |
29 | * | |
30 | * <h2>Mandatory arguments:</h2> | |
31 | * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting --> | |

37 | * <!-- NOTE: ignore the \li. <i> and </i>: it's just doxygen formatting --> | |
38 | * \li -nclusters <i> n </i> <br> | |
39 | * Number of clusters to trigger on. | |
40 | * | |
41 | * By default, configuration is loaded from OCDB, can be overridden by | |
42 | * component arguments. | |
