Constructor & Destructor Documentation

rarSimPdf::rarSimPdf

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 43 of file rarSimPdf.cc.

References init().

  : rarCompBase(),
    _simBuilder(0), _simConfig(0)
{
  init();
}

rarSimPdf::rarSimPdf	(	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, _configFile, _configSec, _configStr, name, title, and then calls init.

Definition at line 63 of file rarSimPdf.cc.

References init().

  : rarCompBase(configFile, configSec, configStr,
                theDatasets, theData, name, title, kFALSE),
    _simBuilder(0), _simConfig(0)
{
  init();
}

RooAbsPdf * rarSimPdf::getPdfWOvar

(

RooArgList

ignoredObs

)

[virtual]

Get a PDF not depending on specified observables for sPlot.

Parameters:

ignoredObs

The observables to check

Returns:

The Pdf required

It checks of the pdf depends on the observables. if no, it returns the default pdf; if yes, it builds the non-dependent pdf.

Reimplemented from rarBasePdf.

Definition at line 125 of file rarSimPdf.cc.

References rarBasePdf::_thePdf.

{
  RooAbsPdf *thePdf=_thePdf;
  cout<<"This pdf can not be used in model"<<endl;
  exit(-1);
  ignoredObs.getHashTableSize() ; // avoid "unused" warning
  return thePdf;
}

RooAbsPdf * rarSimPdf::getProtGen

(

)

[virtual]

Return prototype var generator for toy study.

Returns:

The generator

It constrcuts prototype var generator for toy study

Reimplemented from rarCompBase.

Definition at line 138 of file rarSimPdf.cc.

References rarBasePdf::_theProtGen.

{
  cout<<"This pdf can not be used in model"<<endl;
  exit(-1);
  return _theProtGen;
}

void rarSimPdf::init

(

)

[protected, virtual]

Initial function called by ctor.

init is called by the ctor. The initialization work to read in component config info is done with rarCompBase::init. init here then reads in category info for SimPdf, then it builds datasets for each category type so that each SimPdf component built has its own default fit dataset, and finally it builds RooSimultaneous PDF with configured components.

Reimplemented from rarCompBase.

Definition at line 87 of file rarSimPdf.cc.
