virtual int RequestInformation(vtkInformation *, vtkInformationVector **, vtkInformationVector *)
This is called within ProcessRequest when a request asks for Information.
void PrintSelf(ostream &os, vtkIndent indent)
Methods invoked by print to print information about the object including superclasses.
void GenerateTimeStepIndices(int begin, int end, int step)
Generate a range of indices in [begin, end) with a step size of 'step'.
static vtkExtractTimeSteps * New()
virtual int RequestData(vtkInformation *, vtkInformationVector **, vtkInformationVector *)
This is called within ProcessRequest when a request asks the algorithm to do its work.
void ClearTimeStepIndices()
Clear the time step indices.
int GetNumberOfTimeSteps() const
Get the number of time steps that will be extracted.
