Member Function Documentation

createSeeds() [1/2]

void Acts::Experimental::GraphBasedTrackSeeder::createSeeds	(	const SpacePointContainer &	spacePoints,
		const GbtsRoiDescriptor &	roi,
		const GbtsTrackingFilter &	filter,
		const Options &	options,
		SeedContainer &	outputSeeds ) const

Create seeds from an ACTS space point container in a region of interest.

Convenience wrapper that builds and finalizes the node storage itself. The container must carry the gbtsLayerIndex, clusterWidth and localPositionY columns.

Parameters

spacePoints	Space point container
roi	Region of interest descriptor
filter	Tracking filter to be applied
options	Event based options such as magnetic field strength
outputSeeds	Container with generated seeds

createSeeds() [2/2]

void Acts::Experimental::GraphBasedTrackSeeder::createSeeds	(	GbtsNodeStorage &	nodeStorage,
		const GbtsRoiDescriptor &	roi,
		const GbtsTrackingFilter &	filter,
		const Options &	options,
		SeedContainer &	outputSeeds ) const

Create seeds from a finalized node storage in a region of interest.

Parameters

nodeStorage	Finalized graph node storage
roi	Region of interest descriptor
filter	Tracking filter to be applied
options	Event based options such as magnetic field strength
outputSeeds	Container with generated seeds

makeNodeStorage()

GbtsNodeStorage Acts::Experimental::GraphBasedTrackSeeder::makeNodeStorage

(

)

const

Create an empty node storage matching this seeder's configuration.

Fill it through GbtsNodeStorage::insert, then call GbtsNodeStorage::finalize before handing it to createSeeds.

Returns

An empty node storage
