Class DBObjectChange

java.lang.Object

public class DBObjectChange

extends java.lang.Object

A DBObjectChange is used to notify of changes to a DBObject. It is passed to any appropriate listeners when the provider creates, updates or removes objects. A DBObjectChange is not limited to one type of change, it can contain multiple changes (e.g. children removed as well as children added). A DBObjectChange can include changes to child objects as well through the getOwnedObjectsChanged() method.

Since:

10.1.3
