iguana::clas12::MCProximityMatch Class Reference

#include <Algorithm.h>

Detailed Description

Algorithm: Simple MC truth matching by proximity

Input and Output Banks:

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.
• See also the return value type of this algorithm's action functions, which may be structs with the same set of variables as the created bank.

This algorithm matches reconstructed and generated particles by proximity, and is only meant for older MC files which lack truth-matching banks (MC::GenMatch and MC::RecMatch). You should prefer the truth-matching banks instead, if they are available.

Member Function Documentation

Run() [1/2]

bool iguana::clas12::MCProximityMatch::Run	(	hipo::bank const &	rec_particle_bank,
		hipo::bank const &	mc_particle_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]	rec_particle_bank	REC::Particle bank, the reconstructed particles
[in]	mc_particle_bank	MC::Particle bank, the generated particles
[out]	result_bank	MC::RecMatch::Proximity, which will be created

Returns

true if the created bank is not empty

Run() [2/2]

bool iguana::clas12::MCProximityMatch::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::clas12::MCProximityMatch::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::MCProximityMatch::Stop ( )

overridevirtual

Finalize this algorithm after all events are processed.

Implements iguana::Algorithm.
