// .NAME vtkDataSetToDataSetFilter - abstract filter class
// .SECTION Description
// vtkDataSetToDataSetFilter is an abstract filter class. Subclasses of
// vtkDataSetToDataSetFilter take a dataset as input and create a dataset as
// output. The form of the input geometry is not changed in these filters,
// only the point attributes (e.g. scalars, vectors, etc.).
//
// This is an abstract filter type. What that means is that the output of the
// filter is an abstract type (i.e., vtkDataSet), no matter what the input of
// the filter is. This can cause problems connecting together filters due to
// the change in dataset type. (For example, in a series of filters
// processing vtkPolyData, when a vtkDataSetToDataSetFilter or subclass is
// introduced into the pipeline, if the filter downstream of it takes
// vtkPolyData as input, the pipeline connection cannot be made.) To get
// around this problem, use one of the convenience methods to return a
// concrete type (e.g., vtkGetPolyDataOutput(), GetStructuredPointsOutput(),
// etc.).
