attachSourceLinks()

template<typename propagator_t, typename traj_t>

template<typename track_proxy_t, typename source_link_range_t>

void Acts::Experimental::ReferenceTrajectoryBuilder< propagator_t, traj_t >::attachSourceLinks	(	track_proxy_t	trackProxy,
		const source_link_range_t &	sourceLinkRange,
		const SourceLinkSurfaceAccessor &	surfaceAccessor ) const

Attach source links to the track states in the trajectory based on the reference surfaces and the provided source link range.

Mark track states as holes if no matching source link is found for their reference surface.

Template Parameters

track_proxy_t	The type of the track proxy
source_link_range_t	The type of the source link range, which should be a range of SourceLink objects

Parameters

trackProxy	The track proxy to which the source links will be attached
sourceLinkRange	The range of source links to be attached to the track states
surfaceAccessor	A function or functor that takes a SourceLink and returns a pointer to the corresponding Surface object

build() [1/2]

template<typename propagator_t, typename traj_t>

Result< typename track_container_t::TrackProxy > Acts::Experimental::ReferenceTrajectoryBuilder< propagator_t, traj_t >::build	(	const BoundTrackParameters &	sParameters,
		const Options &	actorOptions,
		const std::vector< const Surface * > &	sSequence,
		track_container_t &	trackContainer ) const

Build the reference trajectory with a given surface sequence and return a track proxy to the built trajectory.

This is only available for DirectNavigator.
