Constructor Detail

VertexView

public VertexView()

Constructs an empty vertex view.

VertexView

public VertexView(java.lang.Object cell)

Constructs a vertex view for the specified model object and the specified child views.

Parameters:

cell - reference to the model object

Method Detail

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 java.awt.geom.Rectangle2D getCachedBounds()

setCachedBounds

public void setCachedBounds(java.awt.geom.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 java.awt.geom.Rectangle2D getBounds()

Returns the cached bounds for the vertex.

Specified by:

getBounds in interface CellView

Overrides:

getBounds in class AbstractCellView

getCenterPoint

public java.awt.geom.Point2D getCenterPoint()

Deprecated. replaced by AbstractCellView.getCenterPoint(CellView vertex)

Returns:

the center point of this vertex

getPerimeterPoint

public java.awt.geom.Point2D getPerimeterPoint(java.awt.geom.Point2D source,
                                      java.awt.geom.Point2D p)

Deprecated. replaced by getPerimeterPoint(EdgeView edge, Point2D source, Point2D p)

getPerimeterPoint

public java.awt.geom.Point2D getPerimeterPoint(EdgeView edge,
                                      java.awt.geom.Point2D source,
                                      java.awt.geom.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
