- Constructor Detail
  - IlvSDMLinkReconnector
```
public IlvSDMLinkReconnector(IlvSDMEngine engine,
                             IlvManagerView view)
```
    Creates a new link reconnector associated with the specified engine and the specified view.
    
    Parameters:
    
    engine - The SDM engine.
    
    view - The manager view in which the reconnection of links will be allowed.
- Method Detail
  - getEngine
```
public IlvSDMEngine getEngine()
```
    Returns the SDM engine with which this link reconnector is associated.
  - getView
```
public IlvManagerView getView()
```
    Returns the manager view with which this link reconnector is associated.
  - setEnabled
```
public void setEnabled(boolean enabled)
```
    Enables or disables the link reconnector.
    
    Parameters:
    
    enabled - If true, the link reconnector is enabled. Otherwise, links cannot be reconnected in the associated view.
  - isEnabled
```
public boolean isEnabled()
```
    Returns the flag indicating whether the link reconnector is enabled.
  - acceptOrigin
```
protected boolean acceptOrigin(Object link,
                               Object origin)
```
    This method is called to verify that an object is a valid origin for the link.
    If the method returns true, the origin object is accepted and the link can be connected to it. Otherwise, the link cannot be connected to the origin object.
    The default implementation always returns true.
  - acceptDestination
```
protected boolean acceptDestination(Object link,
                                    Object destination)
```
    This method is called to verify that an object is a valid destination for the link.
    If the method returns true, the destination object is accepted and the link can be connected to it. Otherwise, the link cannot be connected to the destination object.
    The default implementation always returns true.
  - highlight
```
protected void highlight(Object node)
```
    This method is called to highlight a node when the mouse pointer is over it. The default implementation selects the node.
    
    Parameters:
    
    node - The node to highlight.
    
    Since:
    
    JViews 5.0
  - unHighlight
```
protected void unHighlight(Object node)
```
    This method is called to dehighlight a node when the mouse pointer is no longer over it. The default implementation deselects the node.
    
    Parameters:
    
    node - The node to dehighlight.
    
    Since:
    
    JViews 5.0
  - beginReconnection
```
protected void beginReconnection()
```
    This method is called at the beginning of a reconnection interaction.
    
    Since:
    
    JViews 5.0
  - endReconnection
```
protected void endReconnection()
```
    This method is called at the end of a reconnection interaction.
    
    Since:
    
    JViews 5.0
  - reconnect
```
protected void reconnect(Object node)
```
    This method reconnects the link to a new node. The default implementation calls the setFrom or setTo method of the SDM data model, depending on the result of isReconnectingOrigin().
    
    Parameters:
    
    node - The node to which the link is reconnected.
    
    Since:
    
    JViews 5.0
  - drawLineGhost
```
protected void drawLineGhost(Graphics g)
```
    This method draws the temporary line representing the link during the interaction. The default implementation simply draws a line.
    
    Parameters:
    
    g - The graphic context.
    
    Since:
    
    JViews 5.0
  - getLink
```
public Object getLink()
```
    Returns the link that is being reconnected.
    
    Since:
    
    JViews 5.0
  - isReconnectingOrigin
```
public boolean isReconnectingOrigin()
```
    Returns true if the origin of the link is being reconnected, or false if the destination of the link is being reconnected.
    
    Since:
    
    JViews 5.0
  - getOriginPoint
```
public IlvPoint getOriginPoint()
```
    Returns the origin connection point of the link.
    
    Since:
    
    JViews 5.0
  - getDestinationPoint
```
public IlvPoint getDestinationPoint()
```
    Returns the destination connection point of the link.
    
    Since:
    
    JViews 5.0
  - getCurrentPoint
```
public IlvPoint getCurrentPoint()
```
    Returns the current point where the user has dragged the origin or the destination of the link.
