GetListsSectorPindex()

void iguana::clas12::SectorFinder::GetListsSectorPindex	(	hipo::bank const &	bank,
		std::vector< int > &	sectors,
		std::vector< int > &	pindices ) const

fill lists of sectors and pindices present in the input bank

Parameters

bank	bank from which to get lists of sectors and pindices
sectors	list to fill with sectors in the bank
pindices	list to fill with pindices in the bank

GetSector()

int iguana::clas12::SectorFinder::GetSector	(	std::vector< int > const &	sectors,
		std::vector< int > const &	pindices,
		int const	pindex ) const

Action Function: for a given particle with index pindex, get its sector from a detector bank's list of sectors and pindices (both must be ordered in the same way); nb: this is done instead of finding the pindex in the bank directly, to have an action function

Function Type

vector creator

Example:

//... Initialise algorithms & banks ... 
 
//For each event, do:
 
std::vector<int> sectors;
std::vector<int> pindices
 
//bank is a hipo::bank object from which we want to get the sectors
//for example the bank object related to REC::Calorimeter
for(auto const& row : bank.getRowList()) {
 
    int det=bank.getInt("detector",row);
 
    //NB: you should check you read from an FD detector
    // eg det 7 is the ECAL
    if(det==7){
      sectors.push_back(bank.getInt("sector", row));
      pindices.push_back(bank.getShort("pindex", row));
    }
}
 
//partbank is a hipo::bank object related to REC::Particle
//algo_sector_finder is the iguana::clas12::SectorFinder object
for(auto const& row : partbank.getRowList()) {
    int sector = algo_sector_finder.GetSector(sectors, pindices, row);
}

Parameters

sectors	list of sectors in a detector bank
pindices	list of pindices in a detector bank
pindex	index in REC::Particle bank for which to get sector

Returns

sector for pindex in list, -1 if pindex not in inputted list

Run()

void iguana::clas12::SectorFinder::Run ( hipo::banklist & banks ) const

overridevirtual

Run this algorithm for an event.

Parameters

banks

the list of banks to process

Implements iguana::Algorithm.

Start()

void iguana::clas12::SectorFinder::Start ( hipo::banklist & banks )

overridevirtual

Initialize this algorithm before any events are processed, with the intent to process banks

use this method if you intend to use Algorithm::Run.

Parameters

banks

the list of banks this algorithm will use, so that Algorithm::Run can cache the indices of the banks that it needs

Implements iguana::Algorithm.

Stop()

void iguana::clas12::SectorFinder::Stop ( )

overridevirtual

Finalize this algorithm after all events are processed.

Implements iguana::Algorithm.
