compareTo method

@override int compareTo(MessageStatus 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(MessageStatus other) {
  if (this == other) {
    return 0;
  } else {
    int statusDiff = this.status == null
        ? (other.status == null ? 0 : -1)
        : this.status!.index.compareTo(other.status!.index);
    if (statusDiff != 0) {
      return statusDiff;
    } else {
      return this.messageId == null
          ? (other.messageId == null ? 0 : -1)
          : this.messageId!.compareTo(other.messageId!);
    }
  }
}
