Enum Class NoSnapshotTrigger

java.lang.Object

java.lang.Enum<NoSnapshotTrigger>

io.fluxzero.sdk.persisting.eventsourcing.NoSnapshotTrigger

All Implemented Interfaces:

SnapshotTrigger, Serializable, Comparable<NoSnapshotTrigger>, Constable

public enum NoSnapshotTrigger
extends Enum<NoSnapshotTrigger>
implements SnapshotTrigger

A SnapshotTrigger implementation that never triggers snapshot creation.

This trigger is used by default when snapshotting is explicitly disabled, such as when snapshotPeriod <= 0 is configured on an aggregate via Aggregate.

For many aggregate types this is a suitable default.

• SnapshotTrigger
• Aggregate.snapshotPeriod()
