Class Sequence

java.lang.Object

io.simplesource.data.Sequence

All Implemented Interfaces:

Comparable<Sequence>

public final class Sequence
extends Object
implements Comparable<Sequence>

A monotonically increasing identifier. Each event for a given aggregate has a Sequence starting with 0 for the first event and increasing by one for each event thereafter.
