Hi Martin,

as far as I understand the new at that point is a so-called 'new with placement', i.e. no new memory is allocated, but you write the new object at memory location, which already was use by an object of the same type (and size). This is much faster than new, and you don't need to delete (must not I guess!). This is the general clue of TClonesArrays.

Best,
Klaus
