Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`finish()`	Called when the graph traversal is completed.
`int`	`visit(Graphable element, GraphTraversal traversal)`	Visits a graph component.

- Method Detail
  - visit
```
int visit(Graphable element,
          GraphTraversal traversal)
```
    Visits a graph component.
    
    Parameters:
    
    element - The component being visited.
    
    traversal - The traversal controlling the sequence of graph component visits.
    
    Returns:
    
    GraphTraversal#CONTINUE to signal that the traversal should continue.
    GraphTraversal#CONTINUE to signal that the traversal should suspend.
    GraphTraversal#KILL_BRANCH to signal that the traversal should kill its current branch.
    GraphTraversal#STOP to signal that the traversal should stop.

  - finish
```
void finish()
```
    Called when the graph traversal is completed. Whether this method is called after a traversal has been stopped with a return signal is up to the implementation of GraphTraversal.
