Benjamin,
You could try something like this
Point2D p1;
for (int x = 0; x < oMGeometryList.size(); x++) {
Geometry geometry = (Geometry) oMGeometryList.get(x);
/**
* The Extra level of looping is to deal with multi polygons
* If the geometry is a multi-polygon then the coordinate list is ALL
coordinates
* and they would be connected
*/
for (int g = 0; g < geometry.getNumGeometries(); g++) {
Geometry geo = geometry.getGeometryN(g);
Coordinate[] coords = geo.getCoordinates();
for (int i = 0; i < coords.length; i++) {
p1 = new Point2D.Double(coords[i].x, coords[i].y);
}
}
}
I hope this helps
