19 | // Class AliEvent | |
20 | // Creation and investigation of an Alice physics event. | |
7849a8ab | 21 | // An AliEvent can be constructed by adding AliTracks, Alivertices, AliJets |
7a086578 | 22 | // and/or devices like AliCalorimeters or AliDevice (derived) objects. |
23 | // | |
1c01b4f8 | 24 | // All objects which are derived from TObject can be regarded as a device. |
7a086578 | 25 | // However, AliDevice (or derived) objects profit from additional hit |
26 | // handling facilities. | |
27 | // A "hit" is a generic name indicating an AliSignal (or derived) object. | |
28 | // Note that AliEvent does NOT own hits; it only provides references to hits | |
29 | // obtained from the various devices. | |
30 | // This implies that hits should be owned by the devices themselves. | |
d16062ac | 31 | // |
32 | // The basic functionality of AliEvent is identical to the one of AliVertex. | |
35044448 | 33 | // So, an AliEvent may be used as the primary vertex with some additional |
34 | // functionality compared to AliVertex. | |
d16062ac | 35 | // |
7849a8ab | 36 | // To provide maximal flexibility to the user, the two modes of track/jet/vertex |
37 | // storage as described in AliJet and AliVertex can be used. | |
1c01b4f8 | 38 | // In addition an identical structure is provided for the storage of devices like |
39 | // AliCalorimeter objects, which can be selected by means of the memberfunction | |
40 | // SetDevCopy(). | |
41 | // | |
42 | // a) SetDevCopy(0) (which is the default). | |
43 | // Only the pointers of the 'added' devices are stored. | |
44 | // This mode is typically used by making studies based on a fixed set | |
45 | // of devices which stays under user control or is kept on an external | |
7849a8ab | 46 | // file/tree. |
47 | // In this way the AliEvent just represents a 'logical structure' for the | |
48 | // physics analysis. | |
35044448 | 49 | // |
50 | // Note : | |
1c01b4f8 | 51 | // Modifications made to the original devices also affect the device |
7849a8ab | 52 | // objects which are stored in the AliEvent. |
35044448 | 53 | // |
1c01b4f8 | 54 | // b) SetDevCopy(1). |
55 | // Of every 'added' device a private copy will be made of which the pointer | |
7849a8ab | 56 | // will be stored. |
57 | // In this way the AliEvent represents an entity on its own and modifications | |
58 | // made to the original calorimeters do not affect the AliCalorimeter objects | |
59 | // which are stored in the AliEvent. | |
1c01b4f8 | 60 | // This mode will allow 'adding' many different devices into an AliEvent by |
61 | // creating only one device instance in the main programme and using the | |
62 | // Reset() and parameter setting memberfunctions of the object representing the device. | |
63 | // | |
64 | // Note : | |
65 | // The copy is made using the Clone() memberfunction. | |
66 | // All devices (i.e. classes derived from TObject) have the default TObject::Clone() | |
67 | // memberfunction. | |
68 | // However, devices generally contain an internal (signal) data structure | |
69 | // which may include pointers to other objects. Therefore it is recommended to provide | |
70 | // for all devices a specific copy constructor and override the default Clone() | |
71 | // memberfunction using this copy constructor. | |
7a086578 | 72 | // Examples for this may be seen from AliCalorimeter, AliSignal and AliDevice. |
7849a8ab | 73 | // |
