compareTo method

  1. @override
int compareTo(
  1. ChildVicinity other
)
override

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(ChildVicinity other) {
  if (xIndex == other.xIndex) {
    return yIndex - other.yIndex;
  }
  return xIndex - other.xIndex;
}
