Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`List<E>`	`edgePath()`	Get the path from the source to the last vertex returned by `next()`.
`boolean`	`hasNext()`	Check whether there is more vertices to iterate over.

- Method Detail
  - hasNext
```
boolean hasNext()
```
    Check whether there is more vertices to iterate over.
    
    Specified by:
    
    hasNext in interface Iterator<V>
  - next
```
V next()
```
    Advance the iterator and return a vertex that was not visited by the iterator yet.
    
    Specified by:
    
    next in interface Iterator<V>
  - edgePath
```
List<E> edgePath()
```
    Get the path from the source to the last vertex returned by next().
    The behavior is undefined if next() was not called yet.
    
    Returns:
    
    list of edges forming a path from the source to the last vertex returned by next(). The returned list should not be modified by the user.
