java.lang.Object y.view.EdgeRealizer y.view.SplineEdgeRealizer
public class SplineEdgeRealizer
This realizer draws an edge as a natural cubic spline curve. The bends are interpreted as control points for the curve. This curve type has the property that all control points actually lie on the curve itself.

SplineEdgeRealizer()
Default Constructor. |
|
SplineEdgeRealizer(EdgeRealizer r)
Constructs a new SplineEdgeRealizer as a copy of the given realizer. |
Method Summary | |
---|---|
protected byte |
calculatePath(java.awt.geom.Point2D sourceIntersectionOut,
java.awt.geom.Point2D targetIntersectionOut)
Recalculates the spline path after this realizer has been marked as dirty. |
int |
containsSeg(double dx,
double dy)
like contains(), but returns number of the hit segment, 0 otherwise. |
Bend |
createBend(double x,
double y,
Bend refBend,
int dir)
Adds a new bend before or after the given reference bend. |
EdgeRealizer |
createCopy(EdgeRealizer er)
Creates a copy of this realizer type that is initialized with the attributes of the given realizer. |
Bend |
insertBend(double x,
double y)
Inserts a new bend at location (x,y) into this realizer. |
void |
read(java.io.ObjectInputStream in)
Deprecated. Use the GraphML format instead. |
void |
reInsertBend(Bend bend,
Bend refBend,
int dir)
Reinserts a bend to the edge which had been removed before. |
Bend |
removeBend(Bend b)
Removes a Bend of this realizer |
void |
write(java.io.ObjectOutputStream out)
Deprecated. Use the GraphML format instead. |

into this realizer.
If the given coordinates lie on an visible segment of the spline curve, a new bend will be added that splits the corresponding segment in two parts. Otherwise, no bend is created (e.g. for coordinates very far away from the spline curve).
