Re: class inherited from TClonesArray

Hi,

thanks for the quick replies.
I need a container class for particles, which for example provides functions to do do some combinatorics to reconstruct mother particles. I just thought inheriting from TClonesArray would be an easy way do do this, but I guess I will have to do it some other way, either by forwarding some TClonesArray member functions as Philippe suggested or by putting the additional functions I need into a completely different class.

Cheers,
Jan
