RooClassFactory Class Reference

RooClassFactory is a clase like TTree::MakeClass() that generates skeleton code for RooAbsPdf and RooAbsReal functions given a list of input parameter names.

The factory can also compile the generated code on the fly, and on request also immediate instantiate objects.

Write, compile and load code for a RooAbsReal implementation with class name 'name', taking all elements of 'vars' as constructor arguments.

The initial value expression is taken to be 'expression' which can be any one-line C++ expression in terms of variables that occur in 'vars'. You can add optional expressions for analytical integrals to be advertised by your class in the syntax "<intObsName>:<CPPAnaIntExpression>;<intObsName,intObsName>:<CPPAnaIntExpression>" where <intObsName> a name of the observable integrated over and <CPPAnaIntExpression> is the C++ expression that calculates that integral.
