19 | // Class AliVertex | |
20 | // Creation and investigation of an AliVertex. | |
21 | // An AliVertex can be constructed by adding AliTracks and/or AliJets. | |
22 | // | |
23 | // Note : Also (secondary) vertices can be added to a vertex. | |
24 | // | |
f34f4acb | 25 | // To provide maximal flexibility to the user, two modes of vertex storage |
26 | // are provided by means of the memberfunction SetVertexCopy(). | |
27 | // The same holds for the storage of jets via SetJetCopy(). | |
28 | // | |
29 | // a) SetVertexCopy(0) (which is the default). | |
30 | // Only the pointers of the 'added' vertices are stored. | |
31 | // This mode is typically used by making vertex studies based on a fixed list | |
32 | // of vertices which stays under user control or is contained for instance | |
33 | // in an AliEvent. | |
34 | // In this way the AliVertex just represents a 'logical structure' for the | |
35 | // physics analysis which can be embedded in e.g. an AliEvent or AliVertex. | |
35044448 | 36 | // |
37 | // Note : | |
f34f4acb | 38 | // Modifications made to the original vertices also affect the AliVertex objects |
35044448 | 39 | // which are stored. |
40 | // | |
f34f4acb | 41 | // b) SetVertexCopy(1). |
42 | // Of every 'added' vertex a private copy will be made of which the pointer | |
43 | // will be stored. | |
44 | // In this way the AliVertex represents an entity on its own and modifications | |
45 | // made to the original vertices do not affect the AliVertex objects which are | |
46 | // stored. | |
47 | // This mode will allow 'adding' many different AliVertex objects by | |
48 | // creating only one AliVertex instance in the main programme and using the | |
35044448 | 49 | // AliVertex::Reset, AliVertex::AddTrack and parameter setting memberfunctions. |
