compareTo method
Returns whether this Geometry
is greater than, equal to,
or less than another Geometry
.
If their classes are different, they are compared using the following ordering:
- Point (lowest)
- MultiPoint
- LineString
- LinearRing
- MultiLineString
- Polygon
- MultiPolygon
- GeometryCollection (highest)
Geometry
s have the same class, their first
elements are compared. If those are the same, the second elements are
compared, etc.
@param o a Geometry
with which to compare this Geometry
@return a positive number, 0, or a negative number, depending on whether
this object is greater than, equal to, or less than o
, as
defined in "Normal Form For Geometry" in the JTS Technical
Specifications
Implementation
int compareTo(dynamic o) {
Geometry other = o as Geometry;

}
if (isEmpty() && other.isEmpty()) {
return 0;
}
if (isEmpty()) {
return -1;
}
if (other.isEmpty()) {
return 1;
}
return compareToSameClass(o);
