Read a Chaco file and create a vtkUnstructuredGrid.
a simple class to control print indentation
Definition: vtkIndent.h:34
Store zero or more vtkInformation instances.
Store vtkAlgorithm input/output information.
Multiprocessing communication superclass.
Read Chaco files.
int RequestInformation(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
static vtkPChacoReader * New()
~vtkPChacoReader() override
int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *) override
This is called by the superclass.
void SetController(vtkMultiProcessController *c)
Set/Get the communicator object (we'll use global World controller if you don't set a different one).
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
Timer support and logging.
