StateRevision

value class StateRevision(val value: Long) : Comparable<StateRevision> (source)

Identifies one observation in the ordered history of a state source.

Revisions are non-negative and compare in ascending numeric order. They are meaningful only within one source instance and are never inferred from a snapshot value. A source advances the revision for every newer observation. Once Long.MAX_VALUE is published, that source cannot publish a later snapshot and must fail without mutating or notifying.

Throws

IllegalArgumentException

when StateRevision.value is negative.
