19 | // Class AliEvent | |
20 | // Creation and investigation of an Alice physics event. | |
7849a8ab | 21 | // An AliEvent can be constructed by adding AliTracks, Alivertices, AliJets |
22 | // and/or AliCalorimeters. | |
d16062ac | 23 | // |
24 | // The basic functionality of AliEvent is identical to the one of AliVertex. | |
35044448 | 25 | // So, an AliEvent may be used as the primary vertex with some additional |
26 | // functionality compared to AliVertex. | |
d16062ac | 27 | // |
7849a8ab | 28 | // To provide maximal flexibility to the user, the two modes of track/jet/vertex |
29 | // storage as described in AliJet and AliVertex can be used. | |
30 | // In addition an identical structure is provided for the storage of AliCalorimeter | |
31 | // objects, which can be selected by means of the memberfunction SetCalCopy(). | |
32 | // | |
33 | // a) SetCalCopy(0) (which is the default). | |
34 | // Only the pointers of the 'added' calorimeters are stored. | |
35 | // This mode is typically used by making cal. studies based on a fixed set | |
36 | // of calorimeters which stays under user control or is kept on an external | |
37 | // file/tree. | |
38 | // In this way the AliEvent just represents a 'logical structure' for the | |
39 | // physics analysis. | |
35044448 | 40 | // |
41 | // Note : | |
7849a8ab | 42 | // Modifications made to the original calorimeters also affect the AliCalorimeter |
43 | // objects which are stored in the AliEvent. | |
35044448 | 44 | // |
7849a8ab | 45 | // b) SetCalCopy(1). |
46 | // Of every 'added' calorimeter a private copy will be made of which the pointer | |
47 | // will be stored. | |
48 | // In this way the AliEvent represents an entity on its own and modifications | |
49 | // made to the original calorimeters do not affect the AliCalorimeter objects | |
50 | // which are stored in the AliEvent. | |
51 | // This mode will allow 'adding' many different AliCalorimeters into an AliEvent by | |
52 | // creating only one AliCalorimeter instance in the main programme and using the | |
53 | // AliCalorimeter::Reset() and AliCalorimeter parameter setting memberfunctions. | |
54 | // | |
8e8e6c7f | 55 | // See also the documentation provided for the memberfunction SetOwner(). |
