Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
Perturbs vertices that are coincident.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
