PathGeometry

java.lang.Object
- diva.canvas.interactor.PathGeometry

All Implemented Interfaces:

Geometry
```
public class PathGeometry
extends java.lang.Object
implements Geometry
```
PathGeometry represents a path. Actually, any shape. Its defining shape is any instance of Shape, although generally this class is most useful for shapes that are instances of GeneralPath, since any modification to any of the will cause the shape returned by getShape() to be changed into an instance of GeneralPath.
PathGeometry provides sites for the vertices of the path, and for the control point for those segments that are quadratic or cubic curves.

public PathGeometry(Figure figure,
                    java.awt.Shape shape)
```
    Create a new geometry object on the given figure and with the given initial shape.
- Method Detail
  - getFigure
```
public Figure getFigure()
```
    Get the figure to which this geometry object is attached. Returns null if there isn't one.
    
    Specified by:
    
    getFigure in interface Geometry
  - getShape
```
public java.awt.Shape getShape()
```
    Get the shape that defines this geometry object. If any of the sites have been translated since this shape was set, a new shape will be produced and returned.
    
    Specified by:
    
    getShape in interface Geometry
  - getVertex
```
public Site getVertex(int number)
```
    Get the site on the given vertex.
  - getVertexCount
```
public int getVertexCount()
```
    Get the number of vertices of this shape. This number includes all "Close" segments.
  - setShape
```
public void setShape(java.awt.Shape shape)
```
    Set the shape that defines this geometry object.
    
    Specified by:
    
    setShape in interface Geometry
  - translate
```
public void translate(double x,
                      double y)
```
    Translate the geometry object
    
    Specified by:
    
    translate in interface Geometry
  - vertices
```
public java.util.Iterator vertices()
```
    Return an iteration over the vertices in this geometry object.
