| 23 | \class CGridTransformation |
---|
| 24 | This class is an interface for all transformations to interact with the rest of XIOS. |
---|
| 25 | The class, firstly, tries to get all information relating to requested transformations by retrieving directly from grid. |
---|
[630] | 26 | Then with all these information, all necessary transformations will be created by generic class \class CGenericAlgorithmTransformation. |
---|
[623] | 27 | Because there are information exchange among clients to accomplish the transformations (e.g: some index need retrieving from other clients), |
---|
| 28 | this class uses class \class CTransformationMapping to fulfill this demand. |
---|
| 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 |
