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 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.

NavigationBoundaries navBoundaries = {}

the vector of boundary surfaces to work through

NavigationBoundaryIter navBoundaryIter = navBoundaries.end()

the current boundary iterator of the navigation state

bool navigationBreak = false

Navigation state : a break has been detected.

Stage navigationStage = Stage::undefined
NavigationLayerIter navLayerIter = navLayers.end()

the current layer iterator of the navigation state

NavigationLayers navLayers = {}
