changed - The Persistent object that has changed.

attName - The name of the attribute that has changed.

oldVal - The old values of the attribute.

preChildrenChange

void preChildrenChange(Persistent changing)

This event does not differentiate based on the type of the children. For example, the event is fired for a Subscriber if either its child Subscriptions or child Subscribers are about to change.

Parameters:

changing - The Persistent object whose children are about to change.

postChildrenChange

void postChildrenChange(Persistent changed)

This event is fired after the set of children is changed for the Persistent object for which this PersistentChangeListener is a registered listener.

Parameters:

changed - The Persistent the object whose children have changed.
