Detailed Description

Plain navigator options carrying geometry context and navigation settings.

These are bound to the lifetime of a navigation state and have to be invariant across all runs it serves. Per-run inputs belong into NavigatorInitializeArguments instead.

Member Typedef Documentation

FreeSurfaceSelctor

using Acts::NavigatorPlainOptions::FreeSurfaceSelctor

Initial value:

 Delegate<bool(
      const GeometryContext& gctx, const TrackingVolume& currentVol,
      const Vector3& pos, const Vector3& dir, const Surface& candidate)>

Delegate to decide whether free surfaces are appended to the navigation stream given the current volume and the track coordinates.

If the delegate is set, it is called in each candidate resolution step for each surface that has not been marked as reached yet.

Parameters

gctx	Current geometry context carrying the alignment information
currentVol	The current tracking volume in which the propagator resides
pos	Position of the track in global coordinates
dir	Direction vector of the track
surface	Free surface candidate to test

Constructor & Destructor Documentation

NavigatorPlainOptions()

Acts::NavigatorPlainOptions::NavigatorPlainOptions ( const GeometryContext & gctx )

explicit

NavigatorPlainOptions with context.

Parameters

gctx	The geometry context

Member Function Documentation

appendExternalSurface()

void Acts::NavigatorPlainOptions::appendExternalSurface

(

const Surface &

surface

)

Append an external surface to be considered during navigation.

The surface will be intersected without bounds check to force the propagation to resolve it. Note the surface must outlive the propagation and surfaces have to be added in the order they should be considered during navigation.

Parameters

surface

The surface to add to the list
