a simple class to control print indentation
Definition: vtkIndent.h:113
Iterates over keys of an information object.
void SetInformationWeak(vtkInformation *)
Set the function to iterate over.
virtual void GoToFirstItem()
Move the iterator to the beginning of the collection.
virtual void GoToNextItem()
Move the iterator to the next item in the collection.
void SetInformation(vtkInformation *)
Set/Get the information to iterator over.
static vtkInformationIterator * New()
virtual int IsDoneWithTraversal()
Test whether the iterator is currently pointing to a valid item.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
~vtkInformationIterator() override
virtual vtkInformationKey * GetCurrentKey()
Get the current item.
vtkInformationIteratorInternals * Internal
void InitTraversal()
Move the iterator to the beginning of the collection.
Superclass for vtkInformation keys.
Store vtkAlgorithm input/output information.
