20 | // AliTrackMap.cxx | |
21 | // description: | |
22 | // contains a relation between track label and it's index | |
23 | // in a TreeH. | |
24 | // The main method is At, it takes a particle label as an argument | |
25 | // and returns the correponding entry in TreeH (many particles | |
26 | // are usually stored in 1 TreeH entry, one has to check particle | |
27 | // labels for each hit). 'At' returns: | |
28 | // kNoEntry = -1 if the particle has no entry in TreeH | |
29 | // kOutOfBounds = -2 if the particle label is out of bounds | |
