Class Description

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.
