21 | // AliObjectArray // | |
22 | // // | |
23 | //AliObjectArray is an array of clone (identical) objects. // | |
24 | //In comparison with the TClonesArray objects in this array don't need // | |
25 | //to derive from TObject. They also don't need RTTI - type information. // | |
26 | // // | |
27 | //Objects type information is stored in object fClassInfo (instance of // | |
28 | //the AliClassInfo). // | |
29 | //Objects in array are stored sequentialy in buffers. Buffer is standart C++ // | |
30 | //array of objects. Buffers size is equal for all of the buffers. If we specify | |
31 | //fBufferSize==0 objects are stored in one big standart C++ array. | |
