template<typename spacepoint_t>
class SpacePointBuilder - #include <Acts/SpacePointFormation/SpacePointBuilder.hpp>
After the particle interaction with surfaces are recorded and digitized measurements on the pixel or strip detectors need further treatment.
This class takes the measurements and provides the corresponding space points.

Public Functions
-
SpacePointBuilder(const SpacePointBuilderConfig &cfg, std::function<spacepoint_t(Acts::Vector3, Acts::Vector2, boost::container::static_vector<SourceLink, 2>)> func, std::unique_ptr<const Logger> logger = getDefaultLogger("SpamcePointBuilder", Logging::INFO))
- Parameters
cfg – The configuration for the space point builder
func – The function that provides user’s SP constructor with global pos, global cov, and sourceLinks.
logger – The logging instance

template<template<typename...> typename container_t>
void buildSpacePoint(const GeometryContext &gctx, const std::vector<const Measurement*> &measurements, const SpacePointBuilderOptions &opt, std::back_insert_iterator<container_t<spacepoint_t>> spacePointIt) const Calculates the space points out of a given collection of measurements and stores the results.
- Parameters
gctx – The current geometry context object, e.g. alignment
measurements – vector of measurements
opt – option for the space point bulding. It contains the ends of the strips for strip SP building
spacePointIt – Output iterator for the space point
-
void makeMeasurementPairs(const GeometryContext &gctx, const std::vector<const Measurement*> &measurementsFront, const std::vector<const Measurement*> &measurementsBack, std::vector<std::pair<const Measurement*, const Measurement*>> &measurementPairs) const
Searches possible combinations of two measurements on different surfaces that may come from the same particles.
- Parameters
gctx – The current geometry context object, e.g. alignment
measurementsFront – vector of measurements on a surface
measurementsBack – vector of measurements on another surface
measurementPairs – storage of the measurement pairs
