public interface PersistentEventHandler<P extends Persistent>

This interface provides a hook for some action when an object is inserted, updated or deleted. The methods beforeInsert, beforeUpdate, and beforeDelete are called before the database operation is executed but after the corresponding method of Persistent has been called. The methods afterInsert, afterUpdate, afterDelete and afterRead are called after both the database operation and the corresponding method of Persistent have been executed. Register your event handler using StoreUtil.addEventHandler(PersistentEventHandler, Class[])
