compareTo method

@override int compareTo(XPathAtomic 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(XPathAtomic other) {
  if (other is XPathDateTime) {
    if (type == other.type ||
        (type.isSubtypeOf(xsDateTime) &&
            other.type.isSubtypeOf(xsDateTime))) {
      return utcInstant.compareTo(other.utcInstant);
    }
  }
  return super.compareTo(other);
}
