Constructor & Destructor Documentation

rarHistPdf::rarHistPdf

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 40 of file rarHistPdf.cc.

References init().

  : rarBasePdf(),
    _theHist(0)
{
  init();
}

rarHistPdf::rarHistPdf	(	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 59 of file rarHistPdf.cc.

References init().

  : rarBasePdf(configFile, configSec, configStr,
               theDatasets, theData, name, title),
    _theHist(0)
{
  init();
}

void rarHistPdf::init

(

)

[protected, virtual]

Initial function called by ctor.

init is called by the ctor. It first reads in observable info from config item obs, and use getFormulaArgs to get ArgList of the PDF, and finally it builds RooHistPdf.

Reimplemented from rarBasePdf.

Definition at line 80 of file rarHistPdf.cc.
