| Class | Description | 
|---|---|
| AbstractGraphIterator<V,E> | 
 An empty implementation of a graph iterator to minimize the effort required
 to implement graph iterators. 
 | 
| BreadthFirstIterator<V,E> | 
 A breadth-first iterator for a directed and an undirected graph. 
 | 
| ClosestFirstIterator<V,E> | 
 A closest-first iterator for a directed or undirected graph. 
 | 
| CrossComponentIterator<V,E,D> | 
 Provides a cross-connected-component traversal functionality for iterator
 subclasses. 
 | 
| DepthFirstIterator<V,E> | 
 A depth-first iterator for a directed and an undirected graph. 
 | 
| TopologicalOrderIterator<V,E> | 
 Implements topological order traversal for a directed acyclic graph.
