VectorClock

final case classVectorClock(versions: TreeMap[Node, Long] = TreeMap.empty[VectorClock.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.

5. def :+(node: Node)

Increment the version for the node passed as argument.

Increment the version for the node passed as argument. Returns a new VectorClock.

6. def <(that: VectorClock)

Returns true if `this` is before `that` else false.

7. def <>(that: VectorClock)

Returns true if `this` and `that` are concurrent else false.

8. def ==(that: VectorClock)

Returns true if this VectorClock has the same history as the 'that' VectorClock else false.

13. 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.```
