Detailed Description

Helper class to define constants for the canonical encoding of the CellID0 in tracking sub detectors in ILD (or ILD like detectors).

F.Gaede, DESY, 2011

std::string UTIL::ILDCellID0::encoder_string = "subdet:5,side:-2,layer:9,module:8,sensor:8" [static]

The canonical encoding string to be used for writing the CellID0 with the CellIDEncoder<T>:.

"subdet:5,side:-2,layer:9,module:8:sensor:8"

Use the CellIdDecoder to access the elements:

     CellIDDecoder<TrackerHit> idDec( trkHitCol ) ;
      // ...
      TrackerHit* hit = (TrackerHit*) trkHitCol.getElementAt( i ) ;

      int layer  = idDec( hit )[ ILDCellID0::layer ] ;

const unsigned UTIL::ILDCellID0::module = 3 [static]

Index of the field module in encoder_string - module ID as defined for the given subdetetor.

const unsigned UTIL::ILDCellID0::sensor = 4 [static]

Index of the field sensor in encoder_string - sensor ID as defined for the given subdetetor module.

const unsigned UTIL::ILDCellID0::subdet = 0 [static]

Index of the field subdet in encoder_string - sub detector Id as defined in DetID, e.g.

DetID::VXD or DetID::FTD.
