I'm actually surprised that most of the Shape classes aren't serializable,
but there you have it. Either lack of foresight, or specific design
decision. You might open a feature request to sun, but I doubt it'll get
much traction.
It may be possible to store the segments produced by Area's path iterator
and later reconstitute the area with them. Get the values from the path
iterator and store in your own kind of object. To reconstruct, pass the
segments to GeneralPath move/curve/line operations. This little program
shows how to read the segments. I don't pick off the winding rule here.
public static void main (String args []) {
Area area = new Area ();
area.add(new Area (new Rectangle2D.Double (0, 0, 20.0, 30.0)));
area.add(new Area (new Ellipse2D.Double (-10, -10, 20.0, 20.0)));
PathIterator pi = area.getPathIterator(new AffineTransform ());
double [] pt= new double [6];
while (! pi.isDone()) {
int code = pi.currentSegment(pt);
switch (code) {
case PathIterator.SEG_CLOSE:
System.out.println ("Close "); break;
case PathIterator.SEG_CUBICTO:
System.out.println ("Cubic to (" + pt[0] + "," + pt[1]
+ ") (" + pt[2] + "," + pt[3]
+ ") (" + pt[4] + "," + pt[5] + ")"); break;
case PathIterator.SEG_LINETO:
System.out.println ("Line to (" + pt[0] + "," + pt[1] +
")"); break;
case PathIterator.SEG_MOVETO:
System.out.println ("Move to (" + pt[0] + "," + pt[1] +
")"); break;
case PathIterator.SEG_QUADTO:
System.out.println ("Quad to (" + pt[0] + "," + pt[1]
+ ") (" + pt[2] + "," + pt[3] + ")"); break;
default: System.out.println ("??");
}
pi.next ();
}
