20 // RooRealIntegral performs hybrid numerical/analytical integrals of RooAbsReal objects
21 // The class performs none of the actual integration, but only manages the logic
22 // of what variables can be integrated analytically, accounts for eventual jacobian
23 // terms and defines what numerical integrations needs to be done to complement the
24 // analytical integral.
25 // <p>
26 // The actual analytical integrations (if any) are done in the PDF themselves, the numerical
27 // integration is performed in the various implemenations of the RooAbsIntegrator base class.
