RooAbsRealLValue Class Reference

RooAbsRealLValue is the common abstract base class for objects that represent a real value that may appear on the left hand side of an equation ('lvalue').

Each implementation must provide a setVal() member to allow direct modification of the value. RooAbsRealLValue may be derived, but its functional relation to other RooAbsArg must be invertible

This class has methods that export the defined range of the lvalue, but doesn't hold its values because these limits may be derived from limits of client object. The range serve as integration range when interpreted as a observable and a boundaries when interpreted as a parameter.

PyROOT

Some member functions of RooAbsRealLValue that take a RooCmdArg as argument also support keyword arguments. So far, this applies to RooAbsRealLValue::createHistogram and RooAbsRealLValue::frame. For example, the following code is equivalent in PyROOT:

# Directly passing a RooCmdArg:
frame = x.frame(ROOT.RooFit.Name("xframe"), ROOT.RooFit.Title("RooPlot with decorations"), ROOT.RooFit.Bins(40))
 
# With keyword arguments:
frame = x.frame(Name="xframe", Title="RooPlot with decorations", Bins=40)

overridevirtual

Create an object that represents the integral of the function over one or more observables std::listed in iset.

The actual integration calculation is only performed when the return object is evaluated. The name of the integral object is automatically constructed from the name of the input function, the variables it integrates and the range integrates over. If nset is specified the integrand is request to be normalized over nset (only meaningful when the integrand is a pdf). If rangename is specified the integral is performed over the named range, otherwise it is performed over the domain of each integrated observable. If cfg is specified it will be used to configure any numeric integration aspect of the integral. It will not force the integral to be performed numerically, which is decided automatically by RooRealIntegral.

Implements the following check to see if the value x is in the range [a, b]: check if [x - eps * x, x + eps * x] overlaps with [a, b], where the parameter eps is defined as:

std::max(RooNumber::rangeEpsRel() * std::abs(x), RooNumber::rangeEpsAbs())

By default, RooNumber::rangeEpsRel() and RooNumber::rangeEpsRel() are set to zero. You can change them with RooNumber::setRangeEpsRel(double) and RooNumber::setRangeEpsAbs(double), but this should be only done if there is no other solution.
