Method or function calling interface.

Objects of this class contain the (CINT) environment to call a global function or a method for an object of a specific class with the desired arguments. This class is especially useful when a method has to be called more times for different objects and/or with different arguments. If a function or method needs to be called only once one better uses TInterpreter::Execute().

A limitation is known with the present implementation: failures can occur if parameters involve temporary object construction.

◆ SetParamPtrs()

void TMethodCall::SetParamPtrs	(	void *	paramArr,
		Int_t	nparam = `-1`
	)

ParamArr is an array containing the function argument values.

If nparam = -1 then paramArr must contain values for all function arguments, otherwise Nargs-NargsOpt <= nparam <= Nargs, where Nargs is the number of all arguments and NargsOpt is the number of default arguments.
