3 | // AliFemtoKink: main class holding all the necessary information // | |
4 | // about a kink (before the identification) that is required during // | |
5 | // femtoscopic analysis. This class is filled with information from the // | |
6 | // input stream by the reader. A particle has a link back to the Kink // | |
7 | // it was created from, so we do not copy the information. // | |
