Detailed Description

Geometry helper built from layers and connectors.

Constructor & Destructor Documentation

GbtsGeometry()

Acts::Experimental::GbtsGeometry::GbtsGeometry	(	std::span< const GbtsLayerDescription >	layerDescriptions,
		std::span< const GbtsLayerConnection >	layerConnections,
		float	etaBinWidth,
		const GbtsZ0Range &	z0Range = {},
		const Logger &	logger = getDummyLogger() )

Constructor.

Parameters

layerDescriptions	Layer descriptions for the layers
layerConnections	Pairs of layers the seeder may connect
etaBinWidth	Width of the eta bins each layer is split into
z0Range	z0 range the bin table is built against
logger	Logging instance, only used during construction

Member Function Documentation

binGroups()

std::span< const GbtsBinGroup > Acts::Experimental::GbtsGeometry::binGroups

(

)

const

Get the eta bin pairs the graph is built over, in build order.

Returns

The bin groups

layerBinning()

const GbtsLayerBinning & Acts::Experimental::GbtsGeometry::layerBinning

(

GbtsLayerIndex

idx

)

const

Get the eta binning the geometry gave a layer.

Parameters

idx	Layer index

Returns

Reference to the layer's binning

layerDescription()

const GbtsLayerDescription & Acts::Experimental::GbtsGeometry::layerDescription

(

GbtsLayerIndex

idx

)

const

Get the description a layer was built from.

Parameters

idx	Layer index

Returns

Reference to the layer description

layerIndex()

std::optional< GbtsLayerIndex > Acts::Experimental::GbtsGeometry::layerIndex

(

GbtsExperimentLayerId

id

)

const

Resolve a layer id into the index GbtsNodeStorage::insert takes.

Parameters

id	Layer id, as the layer descriptions carry it

Returns

The layer's index, or nullopt if this geometry has no such layer

numBins()

std::uint32_t Acts::Experimental::GbtsGeometry::numBins

(

)

const

Get the number of eta bins across all layers.

Returns

The bin count

numLayers()

(

)

const

Get the number of layers the geometry was built from.

Returns

The layer count
