Detailed Description

Dataset definition class.

This class defines the dataset structure for the fitter.

Config Directives:

/// Fields = <field01> <field02> ... <fieldN>
/// <field01> = <field01> <varType> ...
/// <field02> = <field02> <varType> ...
/// ...
/// <fieldN> = <fieldN> <varType> ...
/// 
/// AddOns = <addon01> ... <addonM>
/// <addon01> = <addon01> <derivedVarType> ...
/// ...
/// <addonM> = <addonM> <derivedVarType> ...

Fields is a string containing all the names of the variables in data files. The order of the variables should be the same as in the ascii data file. <varType> can be RooRealVar, RooCategory, or RooStringVar. Optional AddOns specifies derived columns for a dataset after it is read in from data file. <addon01>, ..., <addonM> must be derived from other variables declared in Fields. Because all these variables declared here are globally accessible, they should have unique and meaningful names, and it is advisable to have their full names explicitly specified in the config items.

Constructor & Destructor Documentation

rarDatasetDef::rarDatasetDef

(

)

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 38 of file rarDatasetDef.cc.

References init().

  : rarConfig(),
    _primaryObs(0), _addonCols(0)
{
  init();
}

rarDatasetDef::rarDatasetDef	(	const char *	configFile,
		const char *	configSec
	)

Default ctor.

Parameters:

	configFile	The config file
	configSec	The config section

The default ctor initializes common data members, and because there is only one instantiation of this class, _configStr, name and title are set to constant values. It then calls init.

Definition at line 54 of file rarDatasetDef.cc.

References init().

  : rarConfig(configFile, configSec, "null", "DatasetDef", "Dataset Def"),
    _primaryObs(0), _addonCols(0)
{
  init();
}

	)			[private]

virtual RooArgSet* rarDatasetDef::getAddOnCols

(

)

[inline, virtual]

Return addon columns for datasets.

Returns:

The addon columns defined

Reimplemented from rarConfig.

Definition at line 60 of file rarDatasetDef.hh.

References _addonCols.

Referenced by rarDatasets::getAddOnCols().

{return _addonCols;}

RooArgList * rarDatasetDef::getFormulaArgs

(

rarStrParser

fStrParser

)

[virtual]

Get RooFormulaVar ArgList.

Parameters:

fStrParser

The parsed tokens of formula Args

Returns:

The formula ArgList

It creates a RooArgList from fStrParser. It checks if the token in fStrParser is in _fullObs, if not, it creats one by calling createAbsReal, and finally, it adds the var into the ArgList. It repeats until all the tokens are scanned.

Reimplemented from rarConfig.

Definition at line 111 of file rarDatasetDef.cc.

References rarConfig::createAbsReal(), rarConfig::isNumber(), and rarStrParser::nArgs().

{
  RooArgList *depList=new RooArgList;
  Int_t nArgs=fStrParser.nArgs();
  if (nArgs<=0) return depList;
  for (Int_t i=0; i<nArgs; i++) {
    if (isNumber(fStrParser[i])) break;
    RooAbsArg *theDep=createAbsReal(fStrParser[i], fStrParser[i]); // create it
    depList->add(*theDep);
  }
  
  return depList;
}

virtual RooArgSet* rarDatasetDef::getPrimaryObs

(

)

[inline, virtual]

Return primary observables in dataset files.

Returns:

The primary observables defined

Reimplemented from rarConfig.

Definition at line 56 of file rarDatasetDef.hh.

References _primaryObs.

Referenced by rarDatasets::getPrimaryObs().

{return _primaryObs;}

void rarDatasetDef::init

(

)

[protected, virtual]

Initial function called by ctor.

init is called by the ctor. It first reads in the info of fields, and it prints out the fields configured int the config section, then it creates those field variables by calling createAbsVar and adds them to the field list, _fullObs, as final observables.

Reimplemented from rarConfig.

Definition at line 73 of file rarDatasetDef.cc.

}

void rarDatasetDef::setVal	(	TString	var,
		TString	val
	)			[virtual]

Set value for var.

Parameters:

	var	Name of var
	val	Value to set

This function sets value of var defined in _primaryObs
