Class EntityEditEvents

java.lang.Object
is.codion.framework.model.EntityEditEvents
public final class EntityEditEvents extends Object
A central event hub for listening for entity inserts, updates and deletes. You must keep a live reference to any listeners added in order to prevent them from being garbage collected, since listeners are added via a WeakReference. EntityEditModel uses this to post its events.
