Detailed Description

template<typename external_space_point_t, typename grid_t, typename platform_t = void*>
class Acts::SeedFinder< external_space_point_t, grid_t, platform_t >

Seed finder operating on grid-based space points.

Deprecated: This algorithm is deprecated and will be dropped soon. It is replaced by TripletSeeder and the corresponding doublet and triplet seeding helpers.

Constructor & Destructor Documentation

◆ SeedFinder()

template<typename external_space_point_t, typename grid_t, typename platform_t = void*>

Acts::SeedFinder< external_space_point_t, grid_t, platform_t >::SeedFinder	(	const SeedFinderConfig< external_space_point_t > &	config,
		std::unique_ptr< const Logger >	logger = getDefaultLogger("Finder", Logging::Level::INFO) )

explicit

The only constructor.

Requires a config object.

Parameters

config	the configuration for the SeedFinder
logger	the ACTS logger

Create all seeds from the space points in the three iterators.

Can be used to parallelize the seed creation
