Detailed Description

template<typename source_link_t, typename parameters_t>
class Acts::TrackState< source_link_t, parameters_t >

Templated class to hold the track information on a surface along the trajectory.

Template Parameters

source_link_t	Type of the source link
parameters_t	Type of the parameters on the surface

Note: the Surface is only stored as a pointer, i.e. it is assumed the surface lives longer than the TrackState
