Interface: javax.servlet.ServletRequestAttributeListener
- public interface ServletRequestAttributeListener
- implements java.util.EventListener
A ServletRequestAttributeListener can be implemented by the
developer interested in being notified of request attribute
changes. Notifications will be generated while the request
is within the scope of the web application in which the listener
is registered. A request is defined as coming into scope when
it is about to enter the first servlet or filter in each web
application, as going out of scope when it exits the last servlet
or the first filter in the chain.
