#include <itkTreeIteratorBase.h>
This class provides the base implementation for tree iterators.
Events will notify interested observers about tree changes. These events all derive from TreeChangeEvent. They are:
All those events have a member GetChangePosition(), which returns an iterator to the position that has changd. Please note that this iterator may not be fully functional, but you should always be able to use its Get() method to retrieve the thing it points to.
