Detailed Description

Composite base class.

It is the base class for composite PDFs, like AddPdf and ProdPdf. It defines common data and functions for composite PDF upon rarBasePdf.

Config Directives:
/// Comps = <name1> <name2> ... <nameN>
Comps defines names of all its components. Each component has its own config section, namely, comp <name1> is configured in config section named "<name1> Config".
rarCompBase serves as base class for all composite classes and it is not supposed to be referred directly in the config file.

Constructor & Destructor Documentation

rarCompBase::rarCompBase (  ) 

Trivial ctor.

Usually the objects should be created using other ctors.

Definition at line 37 of file rarCompBase.cc.

References init(), and rarBasePdf::setControlBits().

00038   : rarBasePdf(),
00039     _nComp(0)
00040 {
00041   setControlBits("UseBasePdfFit");
00042   init();

rarCompBase::rarCompBase ( const char *  configFile,
const char *  configSec,
const char *  configStr,
rarDatasets *  theDatasets,
RooDataSet *  theData,
const char *  name,
const char *  title,
Bool_t  useBasePdfFit = kTRUE 
)

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
useBasePdfFit If set, use doPdfFit of base class, otherwise, use its own doPdfFit.
The default ctor first initializes data members, _configFile, _configSec, _configStr, name, title, _nComp, UseBasePdfFit, and then calls init.
