compareTo method

@override int compareTo(OptionType 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(final OptionType other) {
  if (optionNumber == other.optionNumber) {
    return 0;
  }

  if (optionNumber < other.optionNumber) {
    return -1;
  }

  return 1;
}
