compareTo method

@override int compareTo(CurrencyAmount 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(CurrencyAmount other) {
  final r = currency.code.compareTo(other.currency.code);
  if (r != 0) {
    return r;
  }
  return amount.compareTo(other.amount);
}
