-
inline AdaptiveMultiVertexFinder(Config &cfg, std::function<BoundTrackParameters(InputTrack_t)> func, std::unique_ptr<const Logger> logger = getDefaultLogger("AdaptiveMultiVertexFinder", Logging::INFO))
Constructor for user-defined InputTrack_t type != BoundTrackParameters.
- Parameters
cfg – Configuration object
func – Function extracting BoundTrackParameters from InputTrack_t object
logger – The logging instance
-
template<typename T = InputTrack_t, std::enable_if_t<std::is_same<T, BoundTrackParameters>::value, int> = 0>
inline AdaptiveMultiVertexFinder(Config &cfg, std::unique_ptr<const Logger> logger = getDefaultLogger("AdaptiveMultiVertexFinder", Logging::INFO)) Constructor used if InputTrack_t type == BoundTrackParameters.
- Parameters
