24 | \class CGridTransformation |
---|
25 | This class is an interface for all transformations to interact with the rest of XIOS. |
---|
26 | The class, firstly, tries to get all information relating to requested transformations by retrieving directly from grid. |
---|
27 | Secondly, with all these information, all necessary transformations will be created by generic class \class CGenericAlgorithmTransformation. |
---|
28 | Then this class accomplishes the transformations by exchanging information among clients (e.g: some index need retrieving index from other clients), |
---|
29 | For each transformation, a new temporary grid source is created. |
---|
30 | For a consequential transformations (e.g: inversing -> zoom -> inversing -> ...), |
---|
31 | the grid destination of current transformation will be grid source of the next transformation |
