Java Enterprise in a Nutshell, Second Edition

Name

HttpSessionAttributeListener

Synopsis

This is a listener interface that allows classes to be notified when attributes are bound or unbound from a session. This listener effectively replaces HttpSessionBindingListener, as the getAttribute() and setAttribute() methods have replaced the getValue() and putValue() methods.

                  
public interface HttpSessionAttributeListener extends java.util.EventListener {
// Public Instance Methods
   public abstract void attributeAdded(
        HttpSessionBindingEvent se);  
   public abstract void attributeRemoved(
        HttpSessionBindingEvent se);  
   public abstract void attributeReplaced(
        HttpSessionBindingEvent se);  
}
