javax.servlet.http.HttpSessionBindingEvent
- All Implemented Interfaces:
Serializable
Events of this type are either sent to an object that implements
HttpSessionBindingListener
when it is bound or unbound from a
session, or to a 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
.
