Struct Acts::DirectNavigator::State

struct State

Nested State struct.

It acts as an internal state which is created for every propagation/extrapolation step and keep thread-local navigation information

Public Functions

inline void reset(const GeometryContext&, const Vector3&, const Vector3&, NavigationDirection, const Surface *ssurface, const Surface *tsurface)

Reset state.

Parameters

• ssurface – is the new starting surface

• tsurface – is the target surface

Public Members

const Surface *currentSurface = nullptr

Navigation state - external interface: the current surface.

const TrackingVolume *currentVolume = nullptr

Navigation state: the current volume.

bool navigationBreak = false

Navigation state - external interface: a break has been detected.

SurfaceIter navSurfaceIter = navSurfaces.begin()

Iterator the next surface.

SurfaceSequence navSurfaces = {}

Externally provided surfaces - expected to be ordered along the path.

const Layer *startLayer = nullptr

Navigation state - starting layer.

const Surface *startSurface = nullptr

Navigation state - external interface: the start surface.

const TrackingVolume *startVolume = nullptr

Navigation state: the start volume.

const Layer *targetLayer = nullptr

Navigation state - target layer.

bool targetReached = false

Navigation state - external interface: target is reached.

const Surface *targetSurface = nullptr

Navigation state - external interface: the target surface.

const TrackingVolume *targetVolume = nullptr

Navigation state: the target volume.
