Examples of org.springframework.web.portlet.context.PortletRequestAttributes

org.springframework.web.portlet.context.PortletRequestAttributes
Portlet-based implementation of the {@link org.springframework.web.context.request.RequestAttributes} interface.
Accesses objects from portlet request and portlet session scope, with a distinction between "session" (the PortletSession's "portlet scope") and "global session" (the PortletSession's "application scope"). @author Juergen Hoeller @since 2.0 @see javax.portlet.PortletRequest#getAttribute @see javax.portlet.PortletSession#getAttribute @see javax.portlet.PortletSession#PORTLET_SCOPE @see javax.portlet.PortletSession#APPLICATION_SCOPE @see RequestAttributes#SCOPE_SESSION @see RequestAttributes#SCOPE_GLOBAL_SESSION
