Examples of javax.portlet.ResourceRequest

javax.portlet.ResourceRequest
The ResourceRequest interface represents the request send to the portlet for rendering resources. It extends the ClientDataRequest interface and provides resource request information to portlets.
The portlet container creates an ResourceRequest object and passes it as argument to the portlet's serveResource method.
The ResourceRequest is provided with the current portlet mode, window state, and render parameters that the portlet can access via the PortletResourceRequest with getPortletMode and, getWindowState, or one of the getParameter methods. ResourceURLs cannot change the current portlet mode, window state or render parameters. Parameters set on a resource URL are not render parameters but parameters for serving this resource and will last only for only this the current serveResource request.
If a parameter is set that has the same name as a render parameter that this resource URL contains, the render parameter must be the last entry in the parameter value array. @see ClientDataRequest @see ResourceServingPortlet @since 2.0

      // extension

      // getting the scopeId is delayed until after getting the FacesContext
      // because a resource request could be as a result of an embedded iFrame
      // i.e. a child scope of the original render -- in this case don't use the render
      // scope but the correct one contained within it
