compareTo method

@override int compareTo(SourceLocation 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(SourceLocation other) {
  if (source != other.source) {
    throw StateError('Cannot compare locations from different sources.');
  }
  return offset - other.offset;
}
