Member Function Documentation

virtual ObjectIntersection<Surface> Acts::ApproachDescriptor::approachSurface ( const GeometryContext &  gctx, const Vector3D &  position, const Vector3D &  direction, const BoundaryCheck &  bcheck  ) const

pure virtual

Get the surface on approach.

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

Returns

is a surface intersection

Implemented in Acts::GenericApproachDescriptor.

virtual const std::vector<const Surface*>& Acts::ApproachDescriptor::containedSurfaces ( ) const
