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.

◆ makeAndCompileFunction()

bool RooClassFactory::makeAndCompileFunction	(	const char *	name,
		const char *	expression,
		const RooArgList &	vars,
		const char *	intExpression = `nullptr`
	)

static

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.

Skeleton code for handling of analytical integrals is added if hasAnaInt is true. 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.
