Interface HttpSessionBindingListener

All Superinterfaces:

EventListener

public interface HttpSessionBindingListener
extends EventListener

Causes an object to be notified when it is bound to or unbound from a session. The object is notified by an HttpSessionBindingEvent object. This may be as a result of a servlet programmer explicitly unbinding an attribute from a session, due to a session being invalidated, or due to a session timing out.
