| 23 | This class is in charge of transfer the global index form grid from grid source to grid destination in a rather generic way. |
---|
| 24 | In order to make a transformation, the grid destination will make a request to grid source about the global indexes which it needs. |
---|
| 25 | The same discovering algorithm as the case of client-server is applied to find the corresponding client which contains the demanding global index. |
