compareTo method

int compareTo(
  1. ContactID o
)
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

int compareTo(ContactID o) {
  return getKey() - o.getKey();
}
