Detailed Description

template<typename source_link_t>
class Acts::MultiTrajectory< source_link_t >

Store a trajectory of track states with multiple components.

This container supports both simple, sequential trajectories as well as combinatorial or multi-component trajectories. Each point can store a parent point such that the trajectory forms a directed, acyclic graph of sub-trajectories. From a set of endpoints, all possible sub-components can be easily identified. Some functionality is provided to simplify iterating over specific sub-components.

Template Parameters

source_link_t Type to link back to an original measurement

Constructor & Destructor Documentation

template<typename source_link_t>

Acts::MultiTrajectory< source_link_t >::MultiTrajectory ( )

default

Create an empty trajectory.

Member Function Documentation

template<typename SL >

size_t MultiTrajectory< SL >::addTrackState	(	TrackStatePropMask	mask = `TrackStatePropMask::All`,
		size_t	iprevious = `SIZE_MAX`
	)

inline

Add a track state without providing explicit information. Which components of the track state are initialized/allocated can be controlled via mask

Parameters

mask	The bitmask that instructs which components to allocate and which to leave invalid
iprevious	index of the previous state, SIZE_MAX if first

Returns: Index of the newly added track state

template<typename SL >

template<typename F >

void MultiTrajectory< SL >::applyBackwards	(	size_t	iendpoint,
		F &&	callable
	)

Apply a function to all previous states starting at a given endpoint.

Parameters

iendpoint	index of the last state
callable	modifying functor to be called with each point

Warning: If the trajectory contains multiple components with common points, this can have an impact on the other components.
