Detailed Description

Interface and a collection of standard implementations for a triplet seed finder.

Note

The standard implementations rely on virtual function dispatch which did not turn out to affect the performance after measurement.

Member Function Documentation

config()

virtual const DerivedConfig & Acts::TripletSeedFinder::config ( ) const

pure virtual

Returns

Reference to the configuration object

create()

std::unique_ptr< TripletSeedFinder > Acts::TripletSeedFinder::create ( const DerivedConfig & config )

static

Creates a new triplet seed finder instance given the configuration.

Parameters

config

Configuration for the triplet seed finder

Returns

Unique pointer to new TripletSeedFinder instance
