Detailed Description

NodeIterator is used to iterate over a tree/list build of objects using a Depth-First-Algorithm. Classes used with the NodeIterator must implement the getChildren() and getOID() methods. NodeIterator implements the 'Iterator Pattern'. The base class NodeIterator defines the interface for all specialized Iterator classes.
