CommDataHandleIF describes the features of a data handle for communication in parallel runs using the Grid::communicate methods. Here the Barton-Nackman trick is used to interprete data handle objects as its interface. Therefore usable data handle classes need to be derived from this class.

Detailed Description
template<class DataHandleImp, class DataTypeImp>
class Dune::CommDataHandleIF< DataHandleImp, DataTypeImp >
CommDataHandleIF describes the features of a data handle for communication in parallel runs using the Grid::communicate methods. Here the Barton-Nackman trick is used to interprete data handle objects as its interface. Therefore usable data handle classes need to be derived from this class.
- Template Parameters:
-
DataHandleImp | implementation of the users data handle |
DataTypeImp | type of data that are going to be communicated which is exported as DataType (for example double) |
