Public Member Functions
	CellIDEncoder (const std::string &cellIDEncoding, EVENT::LCCollection *col)
	Constructor, sets collection parameter LCIO::CellIDEncoding to the given encoding string.
void	setCellID (T *hit)
void	setCellIDFlag ()
	Helper method that sets/unsets the proper bit for storing a second cellid word.
Public Member Functions inherited from UTIL::BitField64
	BitField64 (const std::string &initString)
	The c'tor takes an initialization string of the form: <fieldDesc>[,<fieldDesc>...] fieldDesc = name:[start]:[-]length where: name: The name of the field start: The start bit of the field. More...
lcio::long64	getValue () const
	Returns the current 64bit value.
void	setValue (lcio::long64 value)
	Set a new 64bit value.
void	reset ()
	Reset - same as setValue(0) - useful if the same encoder is used for many objects.
BitFieldValue &	operator[] (size_t theIndex)
	Acces to field through index.
const BitFieldValue &	operator[] (size_t theIndex) const
	Const acces to field through index.
unsigned	highestBit () const
	Highest bit used in fields [0-63].
size_t	size () const
	Number of values.
size_t	index (const std::string &name) const
	Index for field named 'name'.
BitFieldValue &	operator[] (const std::string &name)
	Access to field through name .
const BitFieldValue &	operator[] (const std::string &name) const
	Const Access to field through name .
unsigned	lowWord () const
	The low word, bits 0-31.
unsigned	highWord () const
	The high word, bits 32-63.
std::string	fieldDescription () const
	Return a valid description string of all fields.
std::string	valueString () const
	Return a string with a comma separated list of the current sub field values.

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 ) ;
  }
