Detailed Description

Exponential PDF builder.

Build RooExponential Pdf.

Config Directives:
/// configStr = Exp ["<Optional Title>"]
/// x = AbsReal Def
/// c = AbsReal Def
x is the default observable. c is the exponent of the pdf. All the variables can be RooRealVar or RooFormulaVar.

Constructor & Destructor Documentation

rarExp::rarExp (  ) 

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 40 of file rarExp.cc.

References init().

00041   : rarBasePdf(),
00042     _x(0), _c(0)
00043 {
00044   init();
00045 }

rarExp::rarExp ( 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.

Member Function Documentation

rarExp::ClassDef ( rarExp  ,
0   
) [private]

void rarExp::init (  )  [protected, virtual]

Initial function called by ctor.

init is called by the ctor. It first creates the parameters by calling createAbsReal, and finally it builds the RooExponential PDF.

Reimplemented from rarBasePdf.
