Struct Acts::Navigator::State¶
-
struct Acts::Navigator::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 &geoContext, const Vector3 &pos, const Vector3 &dir, NavigationDirection navDir, const Surface *ssurface, const Surface *tsurface)
Reset state.
- Parameters
geoContext – is the geometry context
pos – is the global position
dir – is the momentum direction
navDir – is the navigation direction
ssurface – is the new starting surface
tsurface – is the target surface
Public Members
-
const Surface *currentSurface = nullptr
Navigation state - external state: the current surface.
-
const TrackingVolume *currentVolume = nullptr
Navigation state: the current volume.
-
ExternalSurfaces externalSurfaces = {}
Externally provided surfaces - these are tried to be hit.
-
bool lastHierarchySurfaceReached = false
Indicator that the last VolumeHierarchy surface was reached skip the next layer targeting to the next boundary/volume.
