Constructor Details
- VertexView
  
  public VertexView()
  
  Constructs an empty vertex view.
- VertexView
  
  public VertexView(Object cell)
  
  Constructs a vertex view for the specified model object and the specified child views.
  
  Parameters:
  
  cell - reference to the model object
Method Details
- update
  
  public void update(GraphLayoutCache cache)
  
  Overrides the parent method to udpate the cached points.
  
  Specified by:
  
  update in interface CellView
  
  Overrides:
  
  update in class AbstractCellView
  
  Parameters:
  
  cache - TODO
- getCachedBounds
  
  public Rectangle2D getCachedBounds()
- setCachedBounds
  
  public void setCachedBounds(Rectangle2D bounds)
- getRenderer
  
  public CellViewRenderer getRenderer()
  
  Returns a renderer for the class.
  
  Specified by:
  
  getRenderer in class AbstractCellView
  
  Returns:
  
  the renderer instance for this view
- getHandle
  
  public CellHandle getHandle(GraphContext context)
  
  Returns a cell handle for the view, if the graph and the view are sizeable.
  
  Specified by:
  
  getHandle in interface CellView
  
  Specified by:
  
  getHandle in class AbstractCellView
  
  Parameters:
  
  context - the context of this cell view (cells indirectly affected by it)
  
  Returns:
  
  the cell handle for this view
- getBounds
  
  public Rectangle2D getBounds()
  
  Returns the cached bounds for the vertex.
  
  Specified by:
  
  getBounds in interface CellView
  
  Overrides:
  
  getBounds in class AbstractCellView
- getCenterPoint
  
  public Point2D getCenterPoint()
  
  Deprecated.
  replaced by AbstractCellView.getCenterPoint(CellView vertex)
  
  Returns:
  
  the center point of this vertex
- getPerimeterPoint
  
  public Point2D getPerimeterPoint(Point2D source, Point2D p)
  
  Deprecated.
  replaced by getPerimeterPoint(EdgeView edge, Point2D source, Point2D p)
- getPerimeterPoint
  
  public Point2D getPerimeterPoint(EdgeView edge, Point2D source, Point2D p)
  
  Returns the intersection of the bounding rectangle and the straight line between the source and the specified point p. The specified point is expected not to intersect the bounds. Note: You must override this method if you use a different renderer. This is because this method relies on the VertexRenderer interface, which can not be safely assumed for subclassers.
  
  Specified by:
  
  getPerimeterPoint in interface CellView
  
  Overrides:
  
  getPerimeterPoint in class AbstractCellView
