Detailed Description

1/2D Keys PDF builder

Build RooKeysPdf / Roo2DKeysPdf Pdf.

Config Directives:

/// configStr = Keys ["<Optional Title>"]
/// configStr = 2DKeys ["<Optional Title>"]
/// x = AbsReal Def
/// y = AbsReal Def
/// rho = Double_t
/// keysOption = Options

x and y are the default observables (y for 2D only). rho is width scale factor. keysOption is 1/2D Keys opitons. For 1D, the options can be any enum value of RooKeysPdf::Mirror, for 2D, the options can be any valid characters of Roo2DKeysPdf::setOptions. All the AbsReal parameters can be RooRealVar or RooFormulaVar.

Constructor & Destructor Documentation

rarKeys::rarKeys

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 41 of file rarKeys.cc.

References init().

  : rarBasePdf(),
    _x(0), _y(0), _rho(1.), _keysOption("")
{
  init();
}

rarKeys::rarKeys	(	const char *	configFile,
		const char *	configSec,
		const char *	configStr,
		rarDatasets *	theDatasets,
		RooDataSet *	theData,
		const char *	name,
		const char *	title
	)

Default ctor.

Parameters:

	configFile	The config file
	configSec	The config section
	configStr	The config string
	theDatasets	Available datasets
	theData	Default dataset for this PDF
	name	The name
	title	The title

The default ctor first initializes data members, and then calls init.

Definition at line 60 of file rarKeys.cc.

References init().

  : rarBasePdf(configFile, configSec, configStr,
               theDatasets, theData, name, title),
    _x(0), _y(0), _rho(1.), _keysOption("")
{
  init();
}

void rarKeys::init

(

)

[protected, virtual]

Initial function called by ctor.

init is called by the ctor.

There is no need to do pdfFit, so the first step is to set _pdfFit to false. It reads in _rho and _keysOption, and finally it builds RooKeysPdf/Roo2DKeysPdf PDF with _pdfType being Keys/2DKeys, respectively.

Reimplemented from rarBasePdf.

Definition at line 84 of file rarKeys.cc.

References _keysOption, rarBasePdf::_pdfType, _rho, rarBasePdf::_theData, rarBasePdf::_thePdf, _x, _y, rarConfig::createAbsReal(), rarBasePdf::getVarSec(), rarConfig::readConfStr(), and rarBasePdf::setControlBits().

void rarKeys::setFitData

(

RooDataSet *

theData = 0

)

[virtual]

Load Keys dataset.

Parameters:

theData

The dataset to be loaded

Load theData as Keys dataset for pdf modeling. There is no need to do pdfFit, instead, 1/2D Keys PDFs call their LoadDataSet/loadDataSet functions to load initial values (datasets).

Reimplemented from rarBasePdf.
