Modifier and Type	Method	Description
`void`	`connectedComponentFinished(ConnectedComponentTraversalEvent e)`	Called to inform listeners that the traversal of the current connected component has finished.
`void`	`connectedComponentStarted(ConnectedComponentTraversalEvent e)`	Called to inform listeners that a traversal of a new connected component has started.
`void`	`edgeTraversed(EdgeTraversalEvent e)`	Called to inform the listener that the specified edge have been visited during the graph traversal.
`void`	`vertexTraversed(VertexTraversalEvent e)`	Called to inform the listener that the specified vertex have been visited during the graph traversal.

- Method Detail
  - connectedComponentFinished
```
void connectedComponentFinished(ConnectedComponentTraversalEvent e)
```
    Called to inform listeners that the traversal of the current connected component has finished.
    
    Parameters:
    
    e - the traversal event.
  - connectedComponentStarted
```
void connectedComponentStarted(ConnectedComponentTraversalEvent e)
```
    Called to inform listeners that a traversal of a new connected component has started.
    
    Parameters:
    
    e - the traversal event.
  - edgeTraversed
```
void edgeTraversed(EdgeTraversalEvent e)
```
    Called to inform the listener that the specified edge have been visited during the graph traversal. Depending on the traversal algorithm, edge might be visited more than once.
    
    Parameters:
    
    e - the edge traversal event.
  - vertexTraversed
```
void vertexTraversed(VertexTraversalEvent e)
```
    Called to inform the listener that the specified vertex have been visited during the graph traversal. Depending on the traversal algorithm, vertex might be visited more than once.
    
    Parameters:
    
    e - the vertex traversal event.
