void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
void Begin(vtkIdTypeArray *) override
Initializes the iterator.
static vtkLabelHierarchyCompositeIterator * New()
virtual void AddIterator(vtkLabelHierarchyIterator *it, int count)
void BoxAllNodes(vtkPolyData *) override
Not implemented.
virtual void AddIterator(vtkLabelHierarchyIterator *it)
Adds a label iterator to this composite iterator.
void GetNodeGeometry(double ctr[3], double &size) override
Retrieve the coordinates of the center of the current hierarchy node and the size of the node.
vtkIdType GetLabelId() override
Retrieves the current label id.
vtkLabelHierarchy * GetHierarchy() override
Retrieve the current label hierarchy.
virtual void ClearIterators()
Remove all iterators from this composite iterator.
bool IsAtEnd() override
Returns true if the iterator is at the end.
void Next() override
Advance the iterator.
