- Method Detail
  - getHeadSite
```
Site getHeadSite()
```
    Get the site that marks the "head" of the connector.
    
    Returns:
    
    the "head" site.
  - getTailSite
```
Site getTailSite()
```
    Get the site that marks the "tail" of the connector.
    
    Returns:
    
    The "tail" site
  - headMoved
```
void headMoved()
```
    Inform the connector that the head site has moved. The connector is expected to reroute itself using an efficient means as is available. Repaint the figure.
  - reroute
```
void reroute()
```
    Tell the connector to re-route itself. In general, implementations of this method should be more efficient than route(). Repaint the figure.
  - route
```
void route()
```
    Tell the connector to route itself completely, using all available information. Repaint the figure.
  - setHeadSite
```
void setHeadSite(Site s)
```
    Set the site that marks the "head" of the connector.
    
    Parameters:
    
    s - The "head" site
  - setTailSite
```
void setTailSite(Site s)
```
    Set the site that marks the "tail" of the connector.
    
    Parameters:
    
    s - The "tail" site
  - tailMoved
```
void tailMoved()
```
    Inform the connector that the tail site has moved. The connector is expected to reroute itself using an efficient means as is available. Repaint the figure.
