Hello, I have an object (derived from TObject) which containes some histograms, like: class A { TH1F *hist1; TH1F *hist2; } The histograms are instantiated in the constructor. After constructing an object of Type A with A* a; I'm going to 'clone' it using something like: A* b = (A*)a->Clone(); Now I get many many warnings like (the object contains about 1000 histograms) Warning in <TH1::Build>: Replacing existing histogram: HiGain000 Is there a simple way to get rid of this warnings when cloning my object (more than once)? Thanks in advance, Thomas.
