Detailed Description

A navigation policy that internally uses the Gen1 SurfaceArray class.

Member Enumeration Documentation

LayerType

enum class Acts::SurfaceArrayNavigationPolicy::LayerType

strong

Enum for configuring which type of surface array to produce.

This affects the projection that is used for creating the binning structure.

Constructor & Destructor Documentation

SurfaceArrayNavigationPolicy()

Acts::SurfaceArrayNavigationPolicy::SurfaceArrayNavigationPolicy ( const GeometryContext & gctx, const TrackingVolume & volume, const Logger & logger, Config config )

explicit

Main constructor, which internally creates the surface array acceleration structure.

Note

Expects that all relevant surfaces are registered with volume. Only selects sensitive surfaces for the surface array.

Parameters

gctx	The geometry context
volume	The layer volume to construct the surface array from
logger	A logging instance
config	The configuration for the surface array

Member Function Documentation

connect()

void Acts::SurfaceArrayNavigationPolicy::connect ( NavigationDelegate & delegate ) const

overridevirtual

Connect this policy with a navigation delegate.

Parameters

delegate

The navigation delegate to connect to

Implements Acts::INavigationPolicy.

initializeCandidates()

void Acts::SurfaceArrayNavigationPolicy::initializeCandidates	(	const GeometryContext &	gctx,
		const NavigationArguments &	args,
		AppendOnlyNavigationStream &	stream,
		const Logger &	logger ) const

Update the navigation state from the surface array.

Parameters

gctx	The geometry context
args	The navigation arguments
stream	The navigation stream to update
logger	The logger

surfaceArray()

const SurfaceArray & Acts::SurfaceArrayNavigationPolicy::surfaceArray

(

)

const

Const reference access to the layer array.

Returns

The surface array
