Hello¡ this is a example, in the multipolygon contain several geometry.
In this case, is the transform the geometry Polygon to contain the
Multipolygon
to LineString.
Geometry geomMulti = multiPolygon.getGeometryN(j);
CoordinateList coordinateList = new CoordinateList();
Vector<Geometry> vectorGeometry = new Vector<Geometry>();
for (int i = 0; i < geomMulti.getCoordinates().length; i++) {
if (coordinateList.size() > 0
&& coordinateList
.contains(geomMulti.getCoordinates()[i])) {
coordinateList.add(geomMulti.getCoordinates()[i], true);
vectorGeometry.add(gf
.createLineString(coordinateList.toCoordinateArray()));
coordinateList = new CoordinateList();
} else {
coordinateList.add(geomMulti.getCoordinates()[i], true);
}
}
goodbye.
