A RooFormulaVar is a generic implementation of a real-valued object, which takes a RooArgList of servers and a C++ expression string defining how its value should be calculated from the given list of servers.

RooFormulaVar uses a RooFormula object to perform the expression evaluation.

If RooAbsPdf objects are supplied to RooFormulaVar as servers, their raw (unnormalized) values will be evaluated. Use RooGenericPdf, which constructs generic PDF functions, to access their properly normalized values.

The string expression can be any valid TFormula expression referring to the listed servers either by name or by their ordinal list position. These three are equivalent:

RooFormulaVar("gen", "x*y", RooArgList(x,y))       // reference by name
RooFormulaVar("gen", "@0*@1", RooArgList(x,y))     // reference by ordinal with @
RooFormulaVar("gen", "x[0]*x[1]", RooArgList(x,y)) // TFormula-builtin reference by ordinal

Note that x[i] is an expression reserved for TFormula. All variable references are automatically converted to the TFormula-native format. If a variable with the name x is given, the RooFormula interprets x[i] as a list position, but x without brackets as the name of a RooFit object.

The last two versions, while slightly less readable, are more versatile because the names of the arguments are not hard coded.
