// .NAME vtkHierarchicalDataIterator - iterator to access datasets in a vtkHierarchicalDataIterator
|
|
// .SECTION Description
|
|
// vtkHierarchicalDataIterator is a concrete implementation of
|
|
// vtkCompositeDataIterator for vtkHierarchicalDataSet. It allows flat
|
|
// and forward access to the datasets in the hierchical dataset.
