Member Function Documentation

Filter()

bool iguana::clas12::ZVertexFilter::Filter	(	double const	zvertex,
		int const	pid,
		int const	status,
		concurrent_key_t const	key ) const

Action Function: checks if the Z Vertex is within specified bounds if pid is one for which the filter should be applied to.; Cuts applied to particles in FD or CD (ie not in FT).

Function Type

scalar filter

Note

This function should be called for each particle

Parameters

zvertex	the particle Z Vertex to check
pid	the particle pid
status	particle status used to check particle is not in FT
key	the return value of PrepareEvent

Returns

true if zvertex is within specified bounds

GetElectronZcuts()

std::vector< double > iguana::clas12::ZVertexFilter::GetElectronZcuts

(

concurrent_key_t const

key

)

const

Parameters

key	the return value of PrepareEvent

Returns

the current z-vertex cuts

GetRunNum()

int iguana::clas12::ZVertexFilter::GetRunNum

(

concurrent_key_t const

key

)

const

Parameters

key	the return value of PrepareEvent

Returns

the current run number

PrepareEvent()

concurrent_key_t iguana::clas12::ZVertexFilter::PrepareEvent

(

int const

runnum

)

const

Action Function: prepare the event

Function Type

reload

Note

This function should be called for each event

Parameters

runnum

the run number

Returns

the key to be used in Filter

Run()

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

overridevirtual

Run this algorithm for an event.

Parameters

banks

the list of banks to process

Implements iguana::Algorithm.

SetElectronZcuts()

void iguana::clas12::ZVertexFilter::SetElectronZcuts	(	double	zcut_lower,
		double	zcut_upper,
		concurrent_key_t const	key )

sets the z-vertex cuts

Warning

this method is not thread safe; instead, for thread safety, use PrepareEvent and a custom configuration file.

Parameters

zcut_lower	the lower bound of the cut
zcut_upper	the upper bound of the cut
key	the, for GetElectronZcuts

Start()

void iguana::clas12::ZVertexFilter::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::ZVertexFilter::Stop ( )

overridevirtual

Finalize this algorithm after all events are processed.

Implements iguana::Algorithm.
