Interface PersistenceEvents

public interface PersistenceEvents

A framework-wide event bus for entity persistence, keyed per EntityType.

Instances are static and shared per entity type (see persistenceEvents(EntityType)). The PersistenceEvents.Inserted, PersistenceEvents.Updated and PersistenceEvents.Deleted events extend Consumer, so any code - not just the editor - may publish persistence events.

• EntityEditor.PUBLISH_PERSISTENCE_EVENTS
• EntityEditor.Settings.publishPersistenceEvents()
• persistenceEvents(EntityType)
