Detailed Description

template<class T>
class UTIL::CellIDEncoder< T >

Specialization for SimTrackerHits that have only one cellID.

Convenient class for encoding cellIDs for various hit objects. It sets the proper collection parameter LCIO::CellIDEncoding and sets the proper flag bit for storing a second cellid if necessary. See UTIL::BitField64 for a description of the encoding string. Example:
CellIDEncoder<SimCalorimeterHitImpl> cd( "i:20,j:20,k:20" ,calVec ) ;
for(int j=0;j<NHITS;j++){
   SimCalorimeterHitImpl* hit = new SimCalorimeterHitImpl ;
   cd["i"] = j ;
   cd["j"] = j + 100 ;
   cd["k"] = j + 200 ;
   cd.setCellID( hit ) ;
}
