12 * @brief Definition of internal dimuon HLT trigger decision data structure
13 * containing decision information for single tracks.
15 * The structures are defined with C linkage since C generally gives us more
16 * binary compatibility between compilers.
19 #include "AliHLTMUONDataTypes.h"
25 * Structure contains information about the trigger decision for a single track.
27 struct AliHLTMUONTrackDecisionStruct
29 AliHLTInt32_t fTrackId; // The ID number of the track we are referring to.
30 // This could also be a trigger record ID.
32 // The trigger bits have the following meaning:
33 // bit: [31 --- 2][ 1 ][ 0 ]
34 // field: reserved hipt lopt
35 // Reserved bits should be set to zero.
36 // hipt == passed high pt cut. lopt == passed low pt cut.
37 AliHLTUInt32_t fTriggerBits;
39 AliHLTFloat32_t fPt; // The calculated transverse momentum of the track in (GeV/c).
43 * AliHLTMUONSinglesDecisionBlockStruct defines the format of the internal
44 * dimuon HLT decision data block for individual tracks.
46 struct AliHLTMUONSinglesDecisionBlockStruct
48 AliHLTMUONDataBlockHeader fHeader; // Common data block header.
49 AliHLTUInt32_t fNlowPt; // Number of low pt triggers.
50 AliHLTUInt32_t fNhighPt; // Number of high pt triggers.
52 // Array of decisions for individual tracks.
53 //AliHLTMUONTrackDecisionStruct fDecision[/*fHeader.fNrecords*/];
60 * Stream operator for usage with std::ostream classes which prints the
61 * trigger decision information for individual tracks in the following format:
