# compareTo method

1. @override

int compareTo(

1. Uuid 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(Uuid other) {
      // Compare most significant bits first
      if (_mostSigBits < other._mostSigBits) return -1;
      if (_mostSigBits > other._mostSigBits) return 1;

      // If most significant bits are equal, compare least significant bits
      if (_leastSigBits < other._leastSigBits) return -1;
      if (_leastSigBits > other._leastSigBits) return 1;

      return 0;
    }
