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_tType to link back to an original measurement

template<typename parameters_t >
size_t Acts::MultiTrajectory< source_link_t >::addTrackState ( const TrackState< SourceLink, parameters_t > &  ts,
size_t  iprevious = SIZE_MAX 
)

Add a track state using information from a separate track state object.

Template Parameters
parameters_tThe parameter type used for the trackstate
Parameters
trackParametersat the local point
ipreviousindex of the previous state, SIZE_MAX if first
Note
The parameter type from parameters_t is not currently stored in MultiTrajectory.
Returns
Index of the newly added track state

template<typename SL >
size_t MultiTrajectory< SL >::addTrackState ( const TrackStatePropMask::Type &  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
maskThe bitmask that instructs which components to allocate and which to leave invalid
ipreviousindex of the previous state, SIZE_MAX if first
Returns
Index of the newly added track state
