Examples of java.beans.beancontext.BeanContextEvent

java.beans.beancontext.BeanContextEvent

BeanContextEvent is the abstract root event class for all events emitted from, and pertaining to the semantics of, a BeanContext. This class introduces a mechanism to allow the propagation of BeanContextEvent subclasses through a hierarchy of BeanContexts. The setPropagatedFrom() and getPropagatedFrom() methods allow a BeanContext to identify itself as the source of a propagated event.
