RooParamBinning Class Reference

Class RooParamBinning is an implementation of RooAbsBinning that constructs a binning with a range definition that depends on external RooAbsReal objects.

The external RooAbsReal definitions are explicitly allowed to depend on other observables and parameters, and make it possible to define non-rectangular range definitions in RooFit. Objects of class RooParamBinning are made by the RooRealVar::setRange() that takes RooAbsReal references as arguments
