Struct Acts::TrackSelector::EtaBinnedConfig

struct EtaBinnedConfig

Main config object for the track selector.

Combines a set of cut configurations and corresponding eta bins

Public Functions

inline EtaBinnedConfig()

Construct an empty (accepts everything) configuration.

Results in a single cut set and one abs eta bin from 0 to infinity.

inline EtaBinnedConfig(Config cutSet)

Auto-converting constructor from a single cut configuration.

Results in a single absolute eta bin from 0 to infinity.

inline EtaBinnedConfig(double etaMin)

Constructor to create a config object that is not upper-bounded.

This is useful to use the “fluent” API to populate the configuration.

Parameters

etaMin – Minimum eta bin edge

inline EtaBinnedConfig(std::vector<double> absEtaEdgesIn)

Constructor from a vector of eta bin edges.

This automatically initializes all the cuts to be the same for all eta and be essentially no-op.

Parameters

absEtaEdgesIn – is the vector of eta bin edges

inline EtaBinnedConfig &addCuts(const std::function<void(Config&)> &callback = {})

Add a new eta bin with an upper bound of +infinity.

Parameters

callback – Callback to configure the cuts for this eta bin

Returns

Reference to this object

inline EtaBinnedConfig &addCuts(double etaMax, const std::function<void(Config&)> &callback = {})

Add a new eta bin with the given upper bound.

Parameters

  • etaMax – Upper bound of the new eta bin

  • callback – Callback to configure the cuts for this eta bin

Returns

Reference to this object

inline std::size_t binIndex(double eta) const

Get the index of the eta bin for a given eta.

Parameters

eta – Eta value

Returns

Index of the eta bin

inline const Config &getCuts(double eta) const

Get the cuts for a given eta.

Parameters

eta – Eta value

Returns

Cuts for the given eta

inline std::size_t nEtaBins() const

Get the number of eta bins.

Returns

Number of eta bins

Public Members

std::vector<double> absEtaEdges = {}

Eta bin edges for varying cuts by eta.

std::vector<Config> cutSets = {}

Cut sets for each eta bin.

Friends

friend std::ostream &operator<<(std::ostream &os, const EtaBinnedConfig &cfg)

Print this configuration to an output stream.

Parameters

  • os – Output stream

  • cfg – Configuration to print

Returns

Reference to the output stream
