Class Description

 RooRealIntegral performs hybrid numerical/analytical integrals of RooAbsReal objects
 The class performs none of the actual integration, but only manages the logic
 of what variables can be integrated analytically, accounts for eventual jacobian
 terms and defines what numerical integrations needs to be done to complement the
 analytical integral.

 The actual analytical integrations (if any) are done in the PDF themselves, the numerical
 integration is performed in the various implemenations of the RooAbsIntegrator base class.

void autoSelectDirtyMode()

 If any of our servers are is forcedDirty or a projectedDependent, then we need to be ADirty

Bool_t servesExclusively(const RooAbsArg* server,const RooArgSet& exclLVBranches) const

 Determine if given server serves exclusively exactly one of the given nodes in exclLVBranches

Bool_t initNumIntegrator() const

 (Re)Initialize numerical integration engine if necessary. Return kTRUE if
 successful, or otherwise kFALSE.

RooRealIntegral(const RooRealIntegral& other, const char* name) : RooAbsReal(other,name), _valid(other._valid), _sumList("sumList",this,other._sumList), _intList("intList",this,other._intList), _anaList("anaList",this,other._anaList), _jacList("jacList",this,other._jacList), _facList("facList","Variables independent of function",this,kFALSE,kTRUE), _facListIter(_facList.createIterator()), _jacListIter(_jacList.createIterator()), _function("function",this,other._function), _iconfig(other._iconfig), _funcACleanBranchIter(_funcACleanBranchList.createIterator()), _mode(other._mode), _operMode(other._operMode), _restartNumIntEngine(kFALSE), _numIntEngine(0), _numIntegrand(0), _rangeName(other._rangeName)

 Copy constructor

~RooRealIntegral() // Destructor

Double_t evaluate() const

void prepareACleanFunc() const

 Make function branch list, if not cached

void restoreACleanFunc() const

 Restore formerly AClean branches to their AClean state

Double_t jacobianProduct() const

 Return product of jacobian terms originating from analytical integration

Double_t sum() const

 Perform summation of list of category dependents to be integrated

Double_t integrate() const

 Perform hybrid numerical/analytical integration over all real-valued dependents

Bool_t redirectServersHook(const RooAbsCollection& /*newServerList*/, Bool_t /*mustReplaceAll*/, Bool_t /*nameChange*/, Bool_t /*isRecursive*/)

Bool_t isValidReal(Double_t /*value*/, Bool_t /*printError*/) const

 Check if current value is valid

void printToStream(ostream& os, PrintOption opt, TString indent) const

 Print the state of this object to the specified output stream.
