virtual int RequestData(vtkInformation *request, vtkInformationVector **inputVector, vtkInformationVector *outputVector)
This is called by the superclass.
Store vtkAlgorithm input/output information.

static vtkUnstructuredGridAlgorithm * New()
int vtkIdType
Definition: vtkType.h:338
int FillInputPortInformation(int port, vtkInformation *info) override
Fill the input port information objects for this algorithm.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
a simple class to control print indentation

dataset represents arbitrary combinations of all possible cell types
Superclass for algorithms that produce only unstructured grid as output.
Store zero or more vtkInformation instances.
