Constructor & Destructor Documentation

◆ TRestComponentFormula()

TRestComponentFormula::TRestComponentFormula	(	const char *	cfgFileName,
		const std::string &	name
	)

Constructor loading data from a config file.

If no configuration path is defined using TRestMetadata::SetConfigFilePath the path to the config file must be specified using full path, absolute or relative.

The default behaviour is that the config file must be specified with full path, absolute or relative.

Parameters

cfgFileName	A const char* giving the path to an RML file.
name	The name of the specific metadata. It will be used to find the corresponding TRestAxionMagneticField section inside the RML.

Definition at line 82 of file TRestComponentFormula.cxx.

Member Function Documentation

◆ FillHistograms()

void TRestComponentFormula::FillHistograms ( )

overrideprotectedvirtual

It will produce a histogram with the distribution using the formula contributions.

For the moment this method will just fill one node (without fParameter). But if the component expression depends on the node parameter it might require further development.

TODO: The histogram is filled just by evaluating the formula, but it would be more realistic that we fill the histograms with a number N of entries that mimic a MC generation scheme similar to TRestComponentDataSet.

Implements TRestComponent.

Definition at line 149 of file TRestComponentFormula.cxx.

◆ GetFormulaRate()

Double_t TRestComponentFormula::GetFormulaRate ( std::vector< Double_t > point )

It returns the intensity/rate (in seconds) corresponding to the formula evaluated at the position of the parameter space given by point and integrated to the parameter space cell volume.

The size of the point vector must have the same dimension as the dimensions of the variables of the distribution.

Definition at line 116 of file TRestComponentFormula.cxx.

◆ InitFromConfigFile()

void TRestComponentFormula::InitFromConfigFile ( )

overrideprotectedvirtual

It customizes the retrieval of XML data values of this class.

For some reason I need to do this manually. Dont understand why!

Reimplemented from TRestComponent.

Definition at line 235 of file TRestComponentFormula.cxx.
