class GenericApproachDescriptor : public Acts::ApproachDescriptor
- #include <Acts/Geometry/GenericApproachDescriptor.hpp>
Class to decide and return which approaching surface to be taken, it’s a generic descriptor for n surfaces.
It is templated in order to allow for BoundarySurfaces from representing volumes of layers to be re-used
Public Functions
A generic approach descriptor for new Acts::Surface objects passing ownership.
- Parameters
aSurfaces – are the approach surfaces
-
~GenericApproachDescriptor() override = default
A generic approach descriptor with n surfaces to test.
-
virtual ObjectIntersection<Surface> approachSurface(const GeometryContext &gctx, const Vector3 &position, const Vector3 &direction, const BoundaryCheck &bcheck) const override
Get the aproach surface to the layer.
- Parameters
gctx – The current geometry context object, e.g. alignment
position – The global position to start the approach from
direction – The momentum vector
bcheck – The boundary check prescription
- Returns
: a SurfaceIntersection
-
virtual const std::vector<const Surface*> &containedSurfaces() const override
return all contained surfaces of this approach descriptor
-
virtual std::vector<const Surface*> &containedSurfaces() override
Non-const version.
-
virtual void registerLayer(const Layer &lay) override
Register the Layer to the surfaces.
- Parameters
lay – is the layer to be registerd
