TH1 all contents within?

ROOT
1

I’m having a little bit of a brainfart. Suppose I have filled a TH1F with bunch of numbers, I want to count the number of all events logged into the TH1F, is there a built in function for it?

I have always used
for int i=0~
counter+=h->GetBinContent(i);

but I was wondering if there was already a built-in function for it? Of course the above method only works, if I’m already know the number of bins.
