How to get a Class member using a string

ROOT
1

Hi,
My problem is as following:
Class TA
{
public:
double value;
}
Class TA a;
Is there any method like a.GetMethod(“value”), in which way we can get the member value using a string.
Thank you very much

Hi,

In which context/for what purpose do you need this?

If is sufficient to get the result as a long you can uselong res = gROOT->ProcessLineFast("a.value");. If you need a double you could try:double result; gROOT->ProcessLine(TString::Format("*(double*)0x%x = a.%s;",&result,"value"));

Cheers,
Philippe.
