23 | * @class AliHLTTriggerBarrelMultiplicity | |
24 | * HLT trigger component for charged particle multiplicity in the | |
25 | * central barrel. | |
26 | * | |
508ca723 | 27 | * Triggers on charged particle number in a certain pt range and geometrical |
28 | * acceptance | |
29 | * | |
30 | * Multiple instances of this component can serve different trigger | |
31 | * conditions, i.e. component parameters. The different instances get | |
32 | * different names, specified by the '-triggername' component argument. | |
33 | * The configuration is loaded from OCDB entries according to the name, see | |
34 | * below. | |
