Member Function Documentation

GetNSegmentsInDet()

int SubDetId::GetNSegmentsInDet ( unsigned long  BitFIeld, SubDetId::SubDetEnum  det  )

static

Method to count the number of Segments a given track has in a detector system The DetMask bitfield masks are used to select the specified detector system

Definition at line 113 of file SubDetId.cxx.

                                                                             {
    return NumberOfSetBits(BitField & DetMask[det]);
}

GetTPC()

int SubDetId::GetTPC ( unsigned long  BitField )

static

Returns the TPC number (TPC1 = 1, TPC2 = 2 etc.) of the track Does not check whether track passed through more than one TPC, just returns the first TPC it finds (checking TPC2, TPC3 then TPC1)

Definition at line 74 of file SubDetId.cxx.

                                          {
    if      (BitField & DetMask[SubDetId::kTPC2]) return 2;
    else if (BitField & DetMask[SubDetId::kTPC3]) return 3;
    else if (BitField & DetMask[SubDetId::kTPC1]) return 1;
    else return -1;
}

SetDetectorSystemFields()

void SubDetId::SetDetectorSystemFields ( unsigned long &  BitField )

static

Method to set the detector system bits using the individual subdetector bits. e.g. If SetDetectorUsed(BitField, SubDetId::kTPC1) had been called, this function would call SetDetectorUsed(BitField, SubDetId::kTPC)

Definition at line 81 of file SubDetId.cxx.

                                                             {

        if (GetDetectorUsed(BitField, static_cast<SubDetId::SubDetEnum>(i))){
            // FGD
            if (i == SubDetId::kFGD1 || i == SubDetId::kFGD2)
              SetDetectorUsed(BitField, SubDetId::kFGD);

            //ECal
            else if (i >= SubDetId::kDSECAL && i <= SubDetId::kRightPECAL){
