Detailed Description

Triplet seed filter used in the triplet seeding algorithm.

Note that this algorithm is designed and tuned for cylindrical detectors and uses R-Z coordinates for the space points.

Constructor & Destructor Documentation

BroadTripletSeedFilter()

Acts::BroadTripletSeedFilter::BroadTripletSeedFilter ( const Config & config, State & state, Cache & cache, const Logger & logger )

explicit

Parameters

config	Configuration parameters for the seed filter
state	Mutable state that is used to store intermediate results
cache	Cache object to store intermediate results
logger	Logger for debugging and information messages

Note

objects from this class depend on a per-event state and cache and should not be used across events.

Member Function Documentation

filterTripletsMiddleFixed()

void Acts::BroadTripletSeedFilter::filterTripletsMiddleFixed ( const SpacePointContainer2 & spacePoints, SeedContainer2 & outputCollection ) const

overridevirtual

Create final seeds for all candidates with the same middle space point.

Parameters

spacePoints	Container with all space points
outputCollection	Output container for the seeds

Implements Acts::ITripletSeedFilter.

filterTripletTopCandidates()

void Acts::BroadTripletSeedFilter::filterTripletTopCandidates ( const SpacePointContainer2 & spacePoints, const ConstSpacePointProxy2 & spM, const DoubletsForMiddleSp::Proxy & bottomLink, const TripletTopCandidates & tripletTopCandidates ) const

overridevirtual

Create seed candidates with fixed bottom and middle space points and all compatible top space points.

Parameters

spacePoints	Container with all space points
spM	Fixed middle space point
bottomLink	Link to the bottom doublet space point
tripletTopCandidates	Collection of triplet top candidates

Implements Acts::ITripletSeedFilter.

sufficientTopDoublets()

bool Acts::BroadTripletSeedFilter::sufficientTopDoublets ( const SpacePointContainer2 & spacePoints, const ConstSpacePointProxy2 & spM, const DoubletsForMiddleSp & topDoublets ) const

overridevirtual

Parameters

spacePoints	Container of space points
spM	Middle space point proxy
topDoublets	Collection of top doublets for the middle space point

Returns

true if sufficient top doublets are found

Implements Acts::ITripletSeedFilter.
