Package io.permazen.change

Class ObjectCreate<T>

java.lang.Object
io.permazen.change.Change<T>
io.permazen.change.ObjectCreate<T>
Type Parameters:
T - the type of the object that was created
public class ObjectCreate<T> extends Change<T>
Change notification that indicates a new object has been created.

This type of change notification is never generated by Permazen itself; object creation notifications are instead delivered to @OnCreate methods, which do not take any parameters. This class exists as a convenience for application code that may want to unify handling of object change and object lifecycle events.
