Class Request

  • Direct Known Subclasses:
    WrapperRequest
    public class Request
extends Message
    Generic request sent by client connectors. It is then received by server connectors and processed by Restlets. This request can also be processed by a chain of Restlets, on both client and server sides. Requests are uniform across all types of connectors, protocols and components.

      • getResourceRef

        public Reference getResourceRef()
        Returns the reference of the target resource. This reference is especially important during routing, dispatching and resource finding. During such processing, its base reference is constantly updated to reflect the reference of the parent Restlet or resource and the remaining part of the URI that must be routed or analyzed. If you need to get the URI reference originally requested by the client, then you should use the getOriginalRef() method instead. Also, note that beside the update of its base property, the resource reference can be modified during the request processing. For example, the TunnelService associated to an application can extract some special extensions or query parameters and replace them by semantically equivalent properties on the request object. Therefore, the resource reference can become different from the original reference. Finally, when sending out requests via a dispatcher such as Context.getClientDispatcher() or Context.getServerDispatcher(), if the reference contains URI template variables, those variables are automatically resolved using the request's attributes.
        Returns:
        The reference of the target resource.
