| | Class VisDerivedDataStrategy<DIM> is an abstract base class that defines an interface allowing an VisItDataWriter<DIM> object and/or an CartesianVizamraiDataWriter<DIM> object to generate plot files that contain "derived" quantities; that is, data that does not reside on the hierarchy, but which is derived from data that does reside on the hierarchy. The derived data may be scalar, vector, or tensor (VisIt only), and cell-centered or node-centered (VisIt only). A concrete object of this type must be registered with the data writer if any derived variable is registered with the data writer. The registration of the concrete strategy object may be done independently using the method setDerivedDataWriter() (Vizamrai only) or setDefaultDerivedDataWriter() (VisIt only) from the relevant DataWriter class, or the concrete strategy object may be registered concurrently with the derived variable using the method registerDerivedPlotScalar/Vector/Tensor().
