void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
Store vtkAlgorithm input/output information.
Superclass for vtkInformation keys.
a simple class to control print indentation
Definition: vtkIndent.h:39
Iterates over keys of an information object.
void InitTraversal()
Move the iterator to the beginning of the collection.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on...
