Constructor Detail

EclipseAndANodeComponent

public EclipseAndANodeComponent(java.lang.String label,
                                java.awt.Point cPoint,
                                java.awt.Dimension b,
                                GNode[] nodesToDraw,
                                java.util.Properties props)

The first node is the reference node

Parameters:

label -

cPoint -

b -

nodesToDraw -

props -

Method Detail

removeShape

public java.util.Collection removeShape(GShape shape)

Overrides:

removeShape in class GraphComponent

preDraw

public void preDraw(java.awt.Graphics g,
                    boolean updateOnly)

Prepare the coordinates of the nodes. For eclipse, we do this in three conceptual steps:
(1) move the eclipse so that its centre point is C(0,0) and the semimajor axis is the x-axis. We work in this coordinate system:
- in this we calculate the tuple (l,x,y) for every point P(x,y), where l is the
distance between P and C
(2) we then transform the eclipse in step 1 by a rotation with an angle theta (which is the angle of the base edge of the semipolygon):
- adjust (l,x,y,alpha) -> (l,x,y, alpha + theta), where alpha is the angle of the line (P,C)
(3) finally, we move the eclipse in step (2) back to the origin D(d1,d2), which is the midpoint of the actual base-edge:
- adjust (l,x,y, alpha + theta) -> (l, x+d1,y+d2, alpha+theta)

Overrides:

preDraw in class GShape

addNodes

public void addNodes(GNode[] nodes,
                     java.awt.Graphics g)

Overrides:

addNodes in class GraphComponent

Parameters:
