| javax.portlet.PortletRequest
All known Subclasses: org.gridsphere.portlet.impl.PortletRequestImpl,
| PortletRequest | | public interface PortletRequest (Code) | | The PortletRequest defines the base interface to provide client
request information to a portlet. The portlet container uses two specialized
versions of this interface when invoking a portlet, ActionRequest
and RenderRequest. The portlet container creates these objects and
passes them as arguments to the portlet's processAction and
render methods.
