public class BeanCreationEvent
extends java.util.EventObject

An event class for reporting the creation of a bean by the dependency injection framework.

Objects of this event class are received by BeanCreationListener implementations, which can be registered at a BeanContext object. Whenever the BeanContext is queried for a bean, and this bean has to be newly created (e.g. because of the first access of a singleton bean or because it is a factory bean), an event of this type is triggered.
