    Specified by:
    
    next in interface java.util.Iterator<BlossomVTreeEdge>
  - getCurrentDirection
```
public int getCurrentDirection()
```
    Returns the direction of the current edge
    
    Returns:
    
    the direction of the current edge
  - advance
```
private BlossomVTreeEdge advance()
```
    Moves this iterator to the next tree edge. If the last outgoing edge has been traversed, changes the current direction to 1. If the the last incoming edge has been traversed, sets currentEdge to null.
    
    Returns:
    
    the next tree edge or null if all edges have been traversed already
