See Run function(s) for the banks that are processed by this algorithm.

Type: Creator

• This algorithm creates new bank(s); click here for a description of all created banks.

ComputeFromLepton()

InclusiveKinematicsVars iguana::physics::InclusiveKinematics::ComputeFromLepton	(	vector_element_t const	lepton_px,
		vector_element_t const	lepton_py,
		vector_element_t const	lepton_pz,
		concurrent_key_t const	key ) const

Action Function: compute kinematics from the scattered lepton.

Function Type

scalar creator

Parameters

lepton_px	scattered lepton momentum component \(p_x\) (GeV)
lepton_py	scattered lepton momentum component \(p_y\) (GeV)
lepton_pz	scattered lepton momentum component \(p_z\) (GeV)
key	the return value of ::PrepareEvent

Returns

the reconstructed inclusive kinematics in a iguana::physics::InclusiveKinematicsVars instance

PrepareEvent()

concurrent_key_t iguana::physics::InclusiveKinematics::PrepareEvent	(	int const	runnum,
		double const	beam_energy = -1 ) const

Action Function: prepare the event

Function Type

reload

Note

This function should be called for each event

Parameters

runnum	the run number
beam_energy	the beam energy; if negative (the default), RCDB will be used to get the beam energy from runnum

Returns

the key to be used in ::ComputeFromLepton

Run() [1/2]

bool iguana::physics::InclusiveKinematics::Run	(	hipo::bank const &	particle_bank,
		hipo::bank const &	config_bank,
		hipo::bank &	result_bank ) 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]	particle_bank	REC::Particle
[in]	config_bank	RUN::config
[out]	result_bank	physics::InclusiveKinematics, which will be created

Returns

true if the kinematics were calculated; e.g., if the calculations are performed using the scattered lepton, and no scattered lepton was found, false will be returned

Run() [2/2]

bool iguana::physics::InclusiveKinematics::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.

Start()

void iguana::physics::InclusiveKinematics::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::physics::InclusiveKinematics::Stop ( )

overridevirtual

Finalize this algorithm after all events are processed.

Implements iguana::Algorithm.
