Detailed Description

Main config object for the track selector.

Combines a set of cut configurations and corresponding eta bins

Constructor & Destructor Documentation

EtaBinnedConfig() [1/4]

Acts::TrackSelector::EtaBinnedConfig::EtaBinnedConfig

(

)

Construct an empty (accepts everything) configuration.

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

EtaBinnedConfig() [2/4]

Acts::TrackSelector::EtaBinnedConfig::EtaBinnedConfig ( double etaMin )

explicit

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

EtaBinnedConfig() [3/4]

Acts::TrackSelector::EtaBinnedConfig::EtaBinnedConfig ( std::vector< double > absEtaEdgesIn )

explicit

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

EtaBinnedConfig() [4/4]

Acts::TrackSelector::EtaBinnedConfig::EtaBinnedConfig ( Config cutSet )

explicit

Auto-converting constructor from a single cut configuration.

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

Parameters

cutSet

Single cut configuration to use for all eta values

Member Function Documentation

addCuts() [1/2]

TrackSelector::EtaBinnedConfig & Acts::TrackSelector::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

addCuts() [2/2]

TrackSelector::EtaBinnedConfig & Acts::TrackSelector::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

binIndex()

std::size_t Acts::TrackSelector::EtaBinnedConfig::binIndex

(

double

eta

)

const

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

throws an exception if Eta is outside the abs eta bin edges.

Parameters

eta

Eta value

Returns

Index of the eta bin

binIndexNoCheck()

std::size_t Acts::TrackSelector::EtaBinnedConfig::binIndexNoCheck

(

double

eta

)

const

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

Parameters

eta

Eta value

Returns

Index of the eta bin, or >= nEtaBins() if Eta is outside the abs eta bin edges.

getCuts()

const TrackSelector::Config & Acts::TrackSelector::EtaBinnedConfig::getCuts

(

double

eta

)

const

Get the cuts for a given eta.

Parameters

eta

Eta value

Returns

Cuts for the given eta

hasCuts()

bool Acts::TrackSelector::EtaBinnedConfig::hasCuts

(

double

eta

)

const

Check if the configuration has a bin for a given eta.

Parameters

eta

Eta value

Returns

True if the configuration has a bin for the given eta

nEtaBins()

std::size_t Acts::TrackSelector::EtaBinnedConfig::nEtaBins

(

)

const

Get the number of eta bins.

Returns

Number of eta bins

Member Data Documentation

absEtaEdges

std::vector<double> Acts::TrackSelector::EtaBinnedConfig::absEtaEdges = {0, inf}

Eta bin edges for varying cuts by eta.

cutSets

std::vector<Config> Acts::TrackSelector::EtaBinnedConfig::cutSets = {}

Cut sets for each eta bin.
