class Acts::ApproachDescriptor

Virtual base class to decide and return which approaching surface to be taken, the surfaces are std::shared_ptr, as they can be the boundary surfaces of the representingVolume of the Layer.

Subclassed by Acts::GenericApproachDescriptor

Public Functions

ApproachDescriptor() = default
~ApproachDescriptor() = default
ObjectIntersection<Surface> approachSurface(const GeometryContext &gctx, const Vector3 &position, const Vector3 &direction, const BoundaryCheck &bcheck) const = 0

Get the surface on approach.

Return

is a surface intersection

Parameters

  • gctx: The current geometry context object, e.g. alignment

  • position: is the position from start of the search

  • direction: is the direction at the start of the search

  • bcheck: is the boundary check directive

const std::vector<const Surface*> &containedSurfaces() const = 0

Get all the contained surfaces.

Return

all contained surfaces of this approach descriptor

std::vector<const Surface*> &containedSurfaces() = 0

Non-const version.

void registerLayer(const Layer &lay) = 0

Register Layer Links the layer to the approach surfaces.

Parameters

  • lay: is the layer to be assigned
