iterator over vtkLabelHierarchy
virtual void Next()
Advance the iterator.
virtual void SetTraversedBounds(vtkPolyData *)
Sets a polydata to fill with geometry representing the bounding boxes of the traversed octree nodes.
virtual void SetHierarchy(vtkLabelHierarchy *h)
The hierarchy being traversed by this iterator.
virtual void GetPoint(double x[3])
Retrieves the current label location.
virtual void BoxNode()
Add a representation to TraversedBounds for the current octree node.
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
virtual vtkStdString GetLabel()
Retrieves the current label string.
virtual void GetNodeGeometry(double ctr[3], double &size)=0
Retrieve the coordinates of the center of the current hierarchy node and the size of the node.
virtual bool IsAtEnd()
Returns true if the iterator is at the end.
virtual vtkIdType GetLabelId()
Retrieves the current label id.
virtual void Begin(vtkIdTypeArray *)
Initializes the iterator.
virtual void BoxAllNodes(vtkPolyData *)
Add a representation for all existing octree nodes to the specified polydata.
virtual void GetBoundedSize(double sz[2])
