20 | // This class for running and define a Trigger Descriptor | |
21 | // | |
22 | // A Trigger Descriptor define a trigger setup for specific runnign | |
23 | // condition (Pb-Pb, p-p, p-A, Calibration, etc). | |
24 | // It keep: | |
25 | // - cluster detector (List of detectors involved) | |
26 | // - List of conditions | |
27 | // | |
28 | // Descriptors could be create in advance and store in a file. | |
29 | // | |
30 | // Example how to create a Trigger Descriptor: | |
31 | // | |
32 | // AliTriggerDescriptor descrip( "TEST", "Test Descriptor" ); | |
33 | // | |
34 | // // Define a Cluster Detector | |
35 | // descrip.AddDetectorCluster( "VZERO ZDC MUON" ); | |
36 | // | |
37 | // // Define the trigger conditions (see AliTriggerCondition.cxx) | |
38 | // descrip.AddCondition( "VZERO_TEST1_L0 & MUON_SPlus_LPt_L0 & ZDC_TEST2_L0", // condition | |
39 | // "VO1_M1_ZDC2", // short name | |
40 | // "Dummy", // short description | |
41 | // 0x0100 ); // class mask (set one bit) | |
42 | // | |
43 | // descrip.AddCondition( "VZERO_TEST2_L0 & MUON_SMinus_HPt_L0 & ZDC_TEST1_L0", | |
44 | // "VO2_M3_ZDC1", | |
45 | // "Dummy", | |
46 | // 0x0200 ); | |
47 | // | |
48 | // descrip.AddCondition( "VZERO_TEST3_L0 | MUON_Unlike_LPt_L0 | ZDC_TEST3_L0", | |
49 | // "VO3_M1_ZDC3", | |
50 | // "Dummy", | |
51 | // 0x0400 ); | |
52 | // descrip.CheckInputsConditions("Config.C"); | |
53 | // descrip.Print(); | |
54 | // | |
55 | // // save the descriptor to file | |
56 | // // (default file name $ALICE_ROOT/data/triggerDescriptor.root) | |
57 | // AliTriggerDescriptor::WriteDescriptor( &descrip ); | |
