HttpSessionBindingEventpublic class HttpSessionBindingEvent extends HttpSessionEvent | Events of this type are either sent to an object that implements
{@link HttpSessionBindingListener} when it is bound or
unbound from a session, or to a {@link HttpSessionAttributeListener}
that has been configured in the deployment descriptor when any attribute is
bound, unbound or replaced in a session.
The session binds the object by a call to
HttpSession.setAttribute and unbinds the object
by a call to HttpSession.removeAttribute. |
