final case class VectorClock(versions: TreeMap[Node, Long] = ...) extends Product with Serializable
Representation of a Vector-based clock (counting clock), inspired by Lamport logical clocks.

Based on code from the 'vlock' VectorClock library by Coda Hale.

def
compareTo(that: VectorClock): Ordering
Compare two vector clocks.
Compare two vector clocks. The outcome will be one of the following:
1. Clock 1 is SAME (==) as Clock 2 iff for all i c1(i) == c2(i) 2. Clock 1 is BEFORE (<) Clock 2 iff for all i c1(i) <= c2(i) and there exist a j such that c1(j) < c2(j) 3. Clock 1 is AFTER (>) Clock 2 iff for all i c1(i) >= c2(i) and there exist a j such that c1(j) > c2(j). 4. Clock 1 is CONCURRENT (<>) to Clock 2 otherwise.
