◆ statistics_accumulator

using statistics_accumulator = bacc::accumulator_set<double, statistics_set>

A boost accumulators set that aggregates statistics for the values it is called with.

It is used to calculate the variables in the extract method. An accumulator set should be created for each category of variables, such as drift length, ADC count, etc. Calling it can be thought of as "filling" it with new values. It then calculates all statistics (corresponding to the final variables) while handling interdependencies in a smart way.

Definition at line 136 of file BasicTrackVarSet.h.

◆ statistics_set

using statistics_set = bacc::features<bacc::tag::count, bacc::tag::sum, bacc::tag::min, bacc::tag::max, bacc::tag::mean, bacc::tag::lazy_variance>

Set of statistics/features to accumulate for each variable category (e.g.

drift length). The statistics set is defined with the boost::accumulator framework, which handles the interdependencies in a smart way. E.g. the calculation of the mean reuses the previously calculated sum. New statistics can be easily added if necessary.

Member Function Documentation

◆ extract()

virtual bool extract ( const Object * obj )

inlinevirtualinherited

Main method that extracts the variable values from the complex object.

Returns indication whether the extraction could be completed successfully. Base implementation returns always true.

Parameters

obj	dummy object not used

Returns: : always true for the base implementation

Definition at line 50 of file BaseVarSet.h.

◆ find()

MayBePtr<Float_t> find ( const std::string & varName )

inlineoverridevirtualinherited

Pointer to the variable with the given name.

Returns nullptr if not found.

Reimplemented from BaseVarSet< AVarNames::Object >.

Definition at line 64 of file VarSet.h.

◆ getNamedValues()

std::map<std::string, Float_t> getNamedValues ( const std::string & prefix ) const

inlineinherited

Getter for a map of names to float values.

Parameters

prefix Name prefix to apply to all variable names.

Definition at line 83 of file BaseVarSet.h.

◆ named()

constexpr static int named ( const char * name )

inlinestaticconstexprprotectedinherited

Getter for the index from the name.

Looks through the associated names and returns the right index if found Returns nVars (one after the last element) if not found.

Parameters

name	Name of the sought variable

Returns: Index of the name, nVars if not found.
