18 | // This class contains all code which is used to compute any of the values | |
19 | // which can be of interest within a resonance analysis. Besides the obvious | |
20 | // invariant mass, it allows to compute other utility values on all possible | |
21 | // targets, in order to allow a wide spectrum of binning and checks. | |
22 | // When needed, this object can also define a binning in the variable which | |
23 | // it is required to compute, which is used for initializing axes of output | |
24 | // histograms (see AliRsnFunction). | |
25 | // The value computation requires this object to be passed the object whose | |
26 | // informations will be used. This object can be of any allowed input type | |
27 | // (track, pair, event), then this class must inherit from AliRsnTarget. | |
28 | // Then, when value computation is attempted, a check on target type is done | |
29 | // and computation is successful only if expected target matches that of the | |
30 | // passed object. | |
31 | // In some cases, the value computation can require a support external object, | |
32 | // which must then be passed to this class. It can be of any type inheriting | |
33 | // from TObject. | |
