compareTo method

@override int compareTo(Geometry other)

Compares this object to another object.

Returns a value like a Comparator when comparing this to other. That is, it returns a negative integer if this is ordered before other, a positive integer if this is ordered after other, and zero if this and other are ordered together.

The other argument must be a value that is comparable to this object.

Implementation

@override
int compareTo(Geometry other) {
  if (geometryType != other.geometryType) {
    return geometryType.code - geometryType.code;
  }
  if (isEmpty() && other.isEmpty()) {
    return 0;
  }
  if (isEmpty()) {
    return -1;
  }
  if (other.isEmpty()) {
    return 1;
  }
  return compareToSameClass(other);
}
