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() [1/2]

bool iguana::clas12::ZVertexFilter::Run	(	hipo::bank &	particleBank,
		hipo::bank const &	configBank ) const

Run Function: Process an event's hipo::bank objects

The parameter list explains which banks are input ("in"), output ("out"), or both ("in,out").

Parameters

[in,out]	particleBank	REC::Particle, which will be filtered
[in]	configBank	RUN::config

Returns: false if all particles are filtered out

◆ Run() [2/2]

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

overridevirtual

Run Function: Process an event's hipo::banklist

Parameters

banks the list of banks to process

Returns: a boolean value, which is typically used to decide whether or not to continue analyzing an event, i.e., it can be used as an event-level filter; not all algorithms use or need this feature; see the algorithm's more specialized Run functions, which have hipo::bank parameters

See also: Specialized Run function(s) above/below; they take individual hipo::bank objects as parameters, and their documentation explains which banks are used by this algorithm and how.

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.
